TIG Welders – Understanding the Advantages and DisAdvantages

Tig Welding

Whilst TIG welding is one of the most preferred methods in the metal industry because it yields the highest quality of welds, it is yet the most complicated processes a welder can become skilled at. Anyone in the welding industry who experienced this welding process will definitely say that in order to attain a great welding job, the TIG method needs an outstanding sense of balance and coordination both physically and mentally.  It takes a lot of training and experience to perfect this method. But once you perfected the skill, it will certainly pay off, big time! To be good at TIG welding, you must dig into what this method is all about, including its advantages and downsides.

Advantages and Downsides

Like any other welding method, TIG has its own shares of advantages and downsides. This can either make or break any welding job. The benefits and disadvantages of each welding method are the primary reason why the metal industry uses a different process depending on the type of the project and the metal to be welded. So, to further understand TIG welding, you have to be aware of the good and bad sides of using this process.

Advantages

  • Highest Weld Quality

Compared to other well known methods, TIG welding has the least amount of cracks, damages, poor weld etc. found during inspection. Moreover, if proper technique is used, it generates a nice benefit of making a weld appear really good. So, for the finest quality of welds, TIG welding is a must!

  • With or Without Filler Metal

TIG welders enjoy both worlds by using or not using filler metals in the process. The choice depends on the welding job at hand. In cases of autogenous welds, the filler metal is not necessary at all. However, some applications consumable filler metal is mandatory to create a weld fill, which is suitable in most applications. But with or without filler metal, TIG welding generates quality weld.

  • Use of Non-consumable Electrode

Compared to other welding method, TIG uses a non-consumable electrode which makes welding a lot easier. This will allow continuity and undisrupted welding operation. Let me explain it further, other method such as Stick welding uses a consumable electrode. In the process of welding, the stick welder needs to halt his operation in order to replace the consummated rod to prevent a bad weld. Otherwise, if he did not change the electrode, the tendency is that, it will produce a bad weld and will impact the overall quality of the finished product. On the other hand, in TIG welding, the process uses a different arc that isn’t greatly affecting the electrode. Thus, there is no need to replace it. This allows a smoother and unceasing operation.

  • Perfect for Non-Ferrous Metals

For most welders, working on non-ferrous metals such as aluminum, magnesium and copper is a tedious job. If a welder is not experienced enough and does not use the suitable welding method, he is doomed to fail. The most suitable method for these kinds of metals is TIG welding. It will yield the least problem compared to other welding method counterparts.

Other Advantages:

  • The consistent outline of this welding process generates the most reliable weld diffusion.
  • Allows greater control of arc length compared to other welding methods. One of the reasons why poor weld exists is due to the inappropriate welding procedure connected to arc length.
  • More concentrated arc
  • Welds two metals and alloys, even thin ones with ease compared to other welding process.
  • No slag of any kind
  • No sparks and spatters

Downsides

  • Safety Concerns

The number one disadvantage of TIG welding comes to safety concerns. The use of non-consumable electrode may come as an advantage, but it is also the primary reason why this method has safety issues. Non-consumable electrodes don’t have a flux coating which commonly covers consumable rods. Flux coating is very essential because it acts as smoke screen which blurs out the light and makes the operation more endurable for the eyes. Hence, TIG welders are more exposed to extreme light which is the same as the light from the sun (Ultraviolet rays) that causes eye damage and may burn the skin. However, the proper used of safety gear such as eye goggles, helmet and the like can remedy this downside.

  • Complicated Welding Method

As mentioned, TIG welding is one of the hardest methods to learn. Basically because you need all the right skill and enough experience before you can perfect this process.  Training is not enough – skill is pretty much has more bearing when it comes to this kind of application. The complexity of TIG welding needs an outstanding sense of balance and coordination. You have to utilize both hands in the process and make sure to adhere to a specific distance between the work piece and the tool to achieve high quality weld. To add up with its complexity, a foot pedal is used most of the time to control the arc needed to join pieces of metals together. TIG can surely be a complicated welding method, but if you master this it will give you a lot of rewards.

  • Slow Welding Method

When it comes to productivity, TIG welding is unreliable. So, for mass production and large welding jobs that need to be done quickly, TIG welding is not utilized because this process consumes a lot of time. However, if you are after a fine weld quality then this process yields the best results.

  • Expensive

The equipment cost together with the materials and sometimes the accessories needed for this method are expensive compared to the other common welding process. However, the advantages and benefits offered by this kind of operation outweigh its expenses. Remember, you always get what you pay for. So, more expensive, higher weld quality.

Other Downsides:

  • Have lower filler metal deposition rates
  • This method utilizes concentrations of shielding gas that may cause build up and can displace oxygen especially when welding is done in confined areas.

Wrapping Up!

While there are advantages and downsides, TIG welding has proven to be one of the best methods employed it the welding industry. Learning this complicated and tedious process is worth it in the long run. Needless to say, quality gets more and more important today than quantity, which makes this method a much sought operation. So, if you are planning a career path towards welding, TIG is the way to go.

Micro TIG Welding Technique

For as long as technology continuously evolves and more and more equipments, gadgets, and the like are being developed the use of welding relatively grows with it. Whether for manufacturing, repairs, molding and a lot more, welding has taken a vital role. Technology makes life so convenient that almost everything is made compact, small, tiny – micro to fit the lifestyle of the people. In relation to this, welding made a breakthrough to accommodate the need to generate these kinds of items. Today, the most common micro welding technique employed is the Micro TIG welding.

Micro TIG welding has emerged from the traditional “heliarc” or TIG welding or more recently termed GTAW (Gas Tungsten Arc Welding). The process is basically the same. Electric current is used to create heat at the point of the arc gap. Then a molten weld puddle is entrenched and a filler rod is set forth into the puddle.

The only difference of Micro TIG welding from the traditional one is that this type of welding is employed at significantly low amperages (below 10 amps) and the amp is consistently controlled at a specific range. This is very salient because the quality of the weld depends on it, besides of course the outstanding skill of the welder. Furthermore, due to the “size” of the welding job, a high-powered (10-10x or more) microscope or a magnifying eye piece is a must for this operation for better visibility and precise welding.

Why TIG Welding?

Most of you know that TIG welding is one of the welding methods that has the highest probability of attaining the finest weld. It is a method which has a specialty process critical when you are after the performance by employing a welding operation as such. The TIG process is preferred because welders are able to control high temperature input, the amount and location of weld puddle to attain a quality weld.

Tips and Bits of Micro TIG Welding

  • Assessment and Preparation

Before starting to employ Micro TIG welding or any welding method for that matter, it is important to assess the whole operation. Are all equipment, tools, and materials in perfect condition? What are the type and grade of metals you will be welding with? The latter is very essential to determine. Most often than not, visual inspection and testing the metals’ hardness rating are essential. This is because you have to plan your “attack” and the information you get from your assessment will determine how the stress of welding will affect these metals. Assessment and proper preparation will yield the best results and prevents mistakes such as cracking and scrapping.

 

  • Cleaning

It is a general rule to clean everything prior to starting a welding operation which includes the tool, equipments and especially the metals. This prevents substances and other contaminants to damage the weld. Cleaning can be as simple as wiping the metals with a solution to remove all dirt and corrosions.

 

  • Low Starting Amperage

It is important to start Micro TIG welding at the very minimum amperage and consistently weld at an extremely low amp range to prevent crater filling and poor welding job. A surge of power during the start can melt the metals before even getting the chance to work with them. Thus, starting low is very crucial. The low amperage should also match the whole operation and the skill level of the welder. Hence, the welding machine along other tools and materials should be of the finest quality that will allow maximum control of the amperage and the heat during welding.

 

  • Micro TIG Torch, Filler Metal and Rods

Micro TIG torch

In Micro TIG welding, the air-cooled torch is commonly used than the water-cooled ones. Well, this is because the use of low amperages does not heat the torch much, hence there is no need for water cooling. In addition, air-cooled torches are a lot cheaper than the other counterpart.

The hardness of the torch body is also important because solid body prevents any chance of shielding gas to escape through a puncture which is a common problem with soft body torches. Moreover, punctures in the torch body allow the air to be sucked into the weld which can result in contamination.

“Tungsten is like a pencil, just like sharper pencils produce sharper writing, sharper tungsten provides better directional control over the arc. Dull tungsten tends to deflect the arc to areas you don’t want to touch.” ~ Matsuo

 The choices of rod size and filler metals are also essential. Rods should range between 0.005” to 0.020” in diameter. On the other hand the filler metal should match the metals to be welded or should be based on the hardness of the final application. Filler metal should be as hard as the metals to be welded to make Texturing possible.

Final Thought

Like any other welding process, the Micro TIG welding has its benefits and drawbacks. But one thing is for certain, this type of welding is a great breakthrough from the traditional welding processes. The definite advantages have given technology opportunities and improvements. The Micro TIG welding has surely fulfilled the welding needs of people in the field.

TIG Welding Settings – What are all those Knobs

TIG welder setup

For some people who are new to welding, knowing the different methods can be quite overwhelming. Sometimes, it is quite surprising to find out that a welding operation just doesn’t happen with a press of a trigger on a welding gun or a torch to join pieces of metals together. Welding is definitely more than that.  When you come face to face with a welding machine, the confusion really sets in. What in the world are all those knobs for?

Knobs for Welding Settings

Well, my friend, those knobs is for welding settings. Crazy as it looks, but it is simple as that. TIG welding can be quite complicated, but it is still one of the best methods that generate the finest weld. FYI is it a welding method which is very in demand nowadays and will surely worth it because it can give a pretty amount of bucks once you get   Anyways, understanding what the knobs are for is pretty essential if you want a precise and accurate end product. However, if you don’t try to educate yourself about all these complexities then you will never get the most out of TIG welding. So, to understand more, here are some of the settings controlled by manipulating these knobs.

  • Amperage

The main control on a TIG machine is the Amperage knob. You can turn the knob depending on the amp needed for the welding job.

  • A/C Balance

As you may know, alternating current consists of a positive and negative electrode moving rapidly back and forth. You can adjust the alternating current by turning the AC balance knob up to 90% dcen depending on the metal you are working with. Bear in mind that for aluminum with corrosion turn the AC balance knob to the maximum dcen while metals with clean plate set the AC balance to 70% – 10% dcen.

  • A/C Frequency

Depending on the welding needed the power utilized is an average of 60 Hz in the US and lesser in some countries at 50 Hz. The incoming AC frequency needs to be powered up before it can be converted to direct current. For this reason, the modern welding machine is smaller compared to traditional ones. The A/C frequency knob allows the use of much higher frequency during TIG welding. This generates a stiffer arc that focuses heat more on the specific point of the work pieces you are welding.

  • Up Slope

Controls the current to climb up to whatever rate you set it in from the amp start to operation amp.

  • Down Slope

This allows the current to decrease to the settings you set it in. This prevents the occurrences of weld defect such as crater crack.

  • 2t

The 2t setting allows the torch to be switched on in 2 positions – control the switch either to get an arc or switch off the arc.

  • 4t

The 4t setting work in conjunction with the upslope and the down slope setting – press the switch to get an arc, turn the knob and the arc up slopes in relation to the amperage you have set or press a button to down slope to lower amperage and switch off to halt the arc.

  • Start Amps

Start amps are very important in TIG welding. You have to start at very low amperage in order not to damage the workpieces.

  • End Amps

The end amperage is also as vital as the start amps. You have to determine the final amperage before the arc quits.

  • Pre-flow

The knob that controls the pre-flow or the time the torch gas flows from the time you press the foot pedal to the time you get the actual arc. Usually this is set to 0.5 second.

  • Post-flow

Post flow knob controls the time the torch gas flows after the arc terminates.

  • Pulse Width

This is the time when the high pulse amperage consistently stays on. It is also known as the Pulse Percentage of time.

  • Peak Pulse Percentage

Also known as the Pulse Percentage of Background Current. This allows you to control the effect of the pulse to limit the heat input or just to generate a weld puddle.

Wrapping Up!

Terms and definitions and names of knobs and TIG setting may vary, but the concepts are basically the same. Setting up a TIG operation requires not only just mere turning of knobs or a flick of a switch. It takes precise calculation, adequate knowledge and enough experience set things up perfectly. For newbies to TIG welding, there are machines sold in the market today with some kind of calculators that are supposed to help a welder set the dials on the TIG machine. However, it is not as reliable as it should be.  Experience and proper training are still the best teachers. So before you turn those knobs and set the TIG welding machine. Get some experience and train with the best.

How to Build your own Router Table

What is the Router Table?

A router table is a fixed wood working mechanism in which an upright oriented spindle of a wood working router extend beyond from the mechanism table and can be rolled at speeds typically between three thousand and twenty four thousand rpm. Cutter heads or the router bits may be ascended in the spindle chuck. As the labour piece or the timber is put into the machine, the cutters will form a outline into it. The machine normally provides a vertical fence, against which the work piece is steered in to control to the horizontal depth of cut. You should read more router table reviews articles here.

router table

Advantages of Router Table

The router table can be used in three kinds of way but in whatever way it may be used, the accessories of the router table is used to guide the wood piece into the router table.  The first use is by using the fence. A fence is used, with the router bit partly budding from the fence. The work piece is then moved alongside the fence, and the uncovered portion of the router bit eradicates material from the work piece. If you are using no fence then you can have a template that is attached to the work piece, and a router bit with a ball manner guide is used. The ball manner guide bears against the template, and the router bit gets rid of material from the work piece so as to create the work piece the same form as the template. And lastly by using a “pin router” accessory. A pin router initially had a pin in the table that would outline the part and hung the router motor on an “over arm” that rose from one edge or corner of the router table, arced over the table, and go down directly towards the pin.

The router table indeed is very useful when doing your wood work however, if you do have the enough budget, the money to actually buy a ready-made router table then you can have a do it yourself router table.

How to make your own Router Table

You can make a router table by using a marine ply wood and two feet of two by four. The first step is to obtain the plastic plate off of the base of your router. Most likely routers have plastic beneath it however you may not do so if your router does not have any. After doing so, you will now trace the plate by putting the hole in the center for the bit to so it could go through. You can also make the hole bigger because the forty five degree edge bit would not fit through the original hole.

Then you can hack a starter hole and then get the jigsaw and completed cutting it out. You have to make sure that when you are tracing the plate to make the pattern of the screw in order that the depth locking mechanism is facing your front when you trace it. You can also get some machine screws; those that fit are the twenty four thread count. You also have to make sure that they are long enough to go through your marine ply wood and to strand into the router base. You should drill the holes that you traced then counter sink. If you do not need the fence then there you have it, your own router table.

However, if you need a fence, then you should put an oblongata hole about four and a half inches from each left and right edge, and about two inches from the far edge of the table and rough on a line. You can strike across the whole table through the middle of the said hole. Then two inches from the far edge and four and a half inches, you can now drill a hole that is four and half inches from the edge and similar from the hole, then cut on a line on the tangents of the two holes you just drilled. You now have an oblongata hole. Then you can do the same procedure on the other side. After put a bolt through the oblongata and the hole in the two by four on both sides and that would serve as the fence of your router table.

You can spend approximately fifteen dollars on the wood and just a few dollars for the screws and bolts.

Different Types Of Wood for Wood Working

There are many types of wood that are utilized for wood working around the globe. Each type of wood has different set of laws for getting the most out of that particular type of wood. In this article, you will  find wood working tips for using these kind of woods with just a small number of of the most well-liked variety of wood used for wood working; wood like the oak, maple, pine and more.

Oak

oak wood

Oak is one of the most popular woods made use of in furniture making. There are many species of oak, but most have very similar qualities for wood working. While oak has a very distinctive, sought-for facade, it can be a complicated wood to work with. However, by following some specific strategy, you can overcome the problems common place to working with oak and get immense marks from your oak wood working projects.

Maple

Maple Wood

Maple is also good for wood working. Maple is another much admired wood used in furniture-building. Maple is quite tough, and when finished using proper methods, will provide a very discrete look. Wood working with maple can be a tiresome experience, chiefly when it comes to applying a finish.

Poplar

Populus Wood

Another popular wood used for wood working is Poplar. Poplar is a more useful-type of hardwood which is commonly used on wood working projects that will be given paint. While poplar can be blemished, it isn’t a very attractive wood with a blemished look, as it often will show brown or gray sections, rather than granule outline, in the wood. A place where poplar does extremely well is as a structural wood, because it is moderately cheap and hard-wearing, making it a perfect choice for carcases, drawer boxes and other similar projects.

Pine

Pine Wood

There is also a wood that you just usually see during Christmas time can also be a good wood for wood working. Pine is one of the three types of soft woods that make up the SPF class, spruce, pine & fir, usually very much available at home stores. However, all pine is not useful, as some stable diversity such as the pine with long leaves that can be used to make some stunning fixtures projects.

Ipe

Ipe Wood

And wood that can be imported is also good for wood working is Ipe. Ipe is a somewhat contentious hardwood from Brazil known for power and water resistance. The debate come around whether the wood may or may not be gathered from a rain forest or from a farm that concentrates in ipe. You may find as many as ten diverse selection of Brazilian ipe at the home stores. While it has a separate form and is usually used as a deck material, there are exact safety measures one should take when running with ipe.

You know well that when you are getting ready to have a project, the preference of which wood material to use can be an overwhelming question. To make the choosing easier, start with thinking about how you want to finish the furniture or the project. Do you want to stain or paint it?

If you decide to paint as your finish, you should not want to waste your money on woods acknowledged for their shade and attractiveness when stained, so avoid darkly-coloured species such as oak, maple, walnut or mahogany. For painted projects, poplar would be a much better choice.

However, if you want to stain or clear-coat the furniture or fixture, you will have a numeral of preference to go through. Since your local home stores and groceries will probably only carry a couple of wood species such as poplar and red oak which are common, give some time at a fine wood dealer and look through the diversity available. They should be able to help you decide how each species will look when finished, which will go a long way toward taming your choice.

Equipments Used in Wood Working

Wood working is the practice of processing wood. It comes in all sorts of forms. Some forms of wood working are boat building, ship building, wood carving, wood turning and carpentry to name some. The equipment used in wood working would actually depend on the form of wood work you are going to do. But generally, there is equipment that is used by people who do wood working.

Types of Equipments used in woodworking.

The equipment used in wood working may be classified into the types of machine.

  • First type of equipment used in wood working are artisanal and hobby machines. Artisanal and hobby machines are usually used by in both small-scale production of commercial timber products and used by those who consider wood working as a hobby. Most of these kinds of equipment are used on solid timber and on complex products. These type of artisanal and hobby machines are also subdivided into two; the bigger equipment which is the stationary equipment where from the name itself the equipment remains in the area, stationary, while the wood is moved over the machine. The other type of equipment is the hand-held powered tools these kinds of equipment from the name itself is portable and can be moved anywhere. These kinds of equipment are moved over to the wood.
  • Examples of stationary equipment are band saw, combination machines, double side planer, four sided planer or timber size, drill press, drum sander, bench grinder, jointer, wood lathe, mortise, panel saw, pin router, radial arm saw, scroll saw, spindle moulder or what is commonly known as wood shaper. There are also stationary sander which includes stroke sanders, oscillating spindle sander, belt sander, disc sander and a combination of disc and belt sander. There are also table saw, tenoner or the tenoning machine. There are also thicknesses or thickness planer, the round pole milling machine and the round pole sanding machine.
  • The second type of artisanal and hobby equipment which is the hand-held power tools also include biscuit joiner, domino jointer, chain saw, hand-held circular saw, electric drill, jig saw, miter saw, nail gun, hand-held electric plane, reciprocating saw, rotary tool, router and those hand-held sanders which also include belt sander, orbital sander and random orbit sander.

Other Types:

The other type of equipment used for wood working is the panel line wood working machines. These types of equipment that are used for wood working are used in large-scale industrialization of cabinets and other wooden or panel products. These types of large-scale equipment are again subdivided into different types depending on what kind of work or process that it does to the wood. There are panel surface processing, panel edge processing equipment and panel boring equipment.

The panel surface processing is also classified into panel dividing equipment which is intended to divide the master panel into different sizes of wood parts. These kinds of panel dividing equipment are also categorized by the number of beams it has, the loading system and its saw carriage speed.  There is also double end tenoner like the rolling chain system conveyor which has the speed of forty to one hundred twenty meters per minute and sliding chain system conveyor which has the speed of ten to thirty meters per minute.

Another kind of panel line wood working equipment is the panel edge processing equipment. These kind of panel line equipment is still classified according to it speed. There is the high speed edge bander conveyor which has the speed of more or less one hundred meter per minute. There is also that heavy duty bander conveyor which has the speed of more or less twenty four meters per minute. There is also the light duty edge bander conveyor which has the speed of more or less twenty meter per minute.

And lastly there is this panel boring equipment which is categorized into the number of boring heads, the single line boring machine and the multi-line boring machine.

Conclusion

Whatever kind of wood working you are doing, whether for a hobby, a small-scale business or the large-scale kind of business you must always choose the right equipment perfectly.

How To Setup Home Karaoke System

Sing along with me (10/365)
Setting up a high and quality karaoke system depends on the ultimate goal and component selection. Whether you intend to use the system for leisure or for commercial purpose, your target is set to up and own that home karaoke system that you desire. Investing in the right and quality components will guarantee you great sound.

There are a lot of factors to consider when putting up a home karaoke system. These basic components are such as mixer, microphone, speakers, monitors, amplifiers, music and various players like the disc players or hard drive players. You can set up a home karaoke system with a disc player with a powered mixer and passive speakers or a karaoke laptop/PC with mixer and powered speakers.

Step1 Connect your disc player.

Home karaoke

A disc player is arguably one of the key components in setting up a karaoke system. Preferably, choose a multi format player that will allow you to play several music formats. A cheap disc player can work too if you’re a beginner so you don’t have to commit a huge budget. Companies like Pioneer, Acesonic and RSQ have quality players.

Step2 Connect your amplifier/mixer.

The important features of a simple karaoke mixer are the key changer, sound effects functions, equaliser, volume control functions, several microphone inputs, standard power (watts e.g. 300W), durable and one that will meet your budget. Some mixer will have lights to indicate the level of volume from each microphone and the mix sent to the amplifier. Yamaha, Azusa and VocoPro have quality mix-amplifiers.

Step3 Connect your microphone.

All current mixers will have microphone inputs. Although many PC have inbuilt mic, it’s always good to budget for a quality microphone. You will use you mixer-amplifier to control effects, tone and volume of your microphone. In certain cases, a cordless microphone can be used but a wired microphone is better because once plugged into a mixer, you can easily move around and adjust settings even as you sing. A Shure microphone is the best to set up a karaoke system with.

Step4 Connect you speakers.

CIMG1473
To determine the sound quality of your karaoke system, you will need the best studio monitors available. These external speakers will be connected to your stereo system or to your stereo player. You cannot compare the output sound from the studio monitors with that of your PC. If you’re taking your laptop outdoors, a small portable Bluetooth speaker would be ideal for you. Most home karaoke speakers should be connected with a standard cable of about 1/4” output. Remember to always put your monitors on stands about 4ft off the ground. (Click here to get more information about best studio monitors.)

When you discuss excellent manufacturers it all relies on the technological innovation and the costs. Beginning from a few $ 100 you can even invest lots of money to make your own house recording studio. The manufacturers available are a lot. Apex 661, Crane song Tracker, dab 160S, De glitch Studio room 400, Drawer Front side End One My, E.A.R./You 660, Evening ESP 4500, Fertile Humanity ‘Fat Peerless’ by TL Audio, Greek deity EQ1 Lunchbox, Joe meek Box V-day, VC2 & SC4 Poppa and C2 Converters L Audio Traditional Compressor & the LA Sound Century Sequence, Vocabulary MPX1 and Vocabulary PCM90, Tackle 1604-VLZ 16 Route Microphone/Line Blender, Jackson Large Passive Radio stations system Pipe E, Violet Audio MC76 limiter, SOL Quire and SOL Pipe Vitalize Asymmetric 628 Digital Speech Mainframe TC Wizard/M2000, TC Digital Fireworks, Thermo ion Lifestyle Arizona, TL Audio ETC device combining table, Worldwide Audio 1176LN etc.

London Falling

IMGL7577
English catwalks looked decidedly bare, although a few youngsters did their best to put on a show — with mixed results, writes Stephen Todd

EVEN by fashion standards, London is having a serious hissy fit. As the autumn-winter 2002 shows kicked off last week, Nicholas Coleridge, managing director of British Vogue and head of the British Fashion Council, took local journalists to task in the pages of The Sunday Times.

The press, he argued, finds it fashionable to knock British fashion designers. If they watched the same collections on the catwalks of Paris or Milan, they would write rave reviews, but seeing them here, in their own back yard, they will cavil.

“Nonsense,” parried The Sunday Times fashion editor Colin McDowell. “If our designers want to play on a world stage, it does them an absolute disservice to be handled with kid gloves at home. They need to be able to listen to criticism and perhaps even act on it!”

The polemic is the product of London’s fashion crisis. Deserted by its home-grown finest, the city that has swung off and on since the 1960s is finding its dance card less than full. John Galliano took his romantic antics to Paris years ago, followed by Vivienne Westwood, bovver boy Alexander McQueen, rock chick Stella McCartney, brainiac Hussein Chalayan and, this season, the king and queen of street cool, Clements-Ribeiro.

“We were snubbed quite a bit after we decided to show in Paris,” Inacio Ribeiro admits. “But what were our choices?” Indeed, the duo’s lucrative contract with French house Cacharel means that moving their label’s show to the one capital where all the international press go without fail makes business sense.

And there’s the rub. Although the mass exodus to Paris (plus Matthew Williamson’s decision to show in New York and Antonio Berardi’s opting for Milan) has created a name drain in London, it’s difficult to fault the decision to show offshore. Fact is, with an international show schedule that can have editors out of their offices for up to six weekstwice a year (without even counting menswear or couture), taking the mountain to Mohammed has never looked so good.
Old Independent Apostolic Lutheran Church
The result is a city renowned for its bravado, its eccentricity and its irrepressible energy fuelled by an active club-drug-music-street-style culture left sitting on the sidelines for a time. “I find myself embarrassed at London Fashion Week,” confides one local fashion journo who asks to remain nameless. “And I’m so over finding myself stuck at some dingy fruit market in the middle of nowhere at 11pm to see clothes that are actually quite dreadful and that I’m supposed to write something positive about.”

“They’re all brats,” laughs my designer Deep Throat. “They think that since they managed to graduate from art school they should be able to show and to be lauded.” But as we know, it doesn’t work quite like that.

There are interesting designers in London, but they live with the constant pressure to be as good as, if not better than, the incredible talents that preceded them. What’s more, they live and work in a city synonymous with in-yer-face attitude when the global market is thriving on easily consumable cool. As master Brit milliner Stephen Jones puts it: “Here, fashion is constantly looking for the next thing, it’s a phoenix that keeps rising from the ashes. Unfortunately, there are a lot of ashes.” Burning bright for a season or so, then fading fast is not at all uncommon.

“London is quite valuable for designers to learn to make collections and put on shows,” reckons Susannah Frankel, fashion editor of The Independent. “And it’s the only city where a relative outsider can assemble 200 quite high-ranking journalists in one room to present a collection that is still quite green. Whether you see that as a good thing or a bad thing depends on who you are.”
France-003080 - Place de la Liberation
Bernard Arnault, Domenico de Sole, Francois Pinault and many other Euroluxe bigwigs have clearly seen that as a good thing, since they were the first to tap the dynamism London so readily produced. And now? “London: a capital deserted by fashion,” French daily paper Liberation smirked after this round of shows. Yet that’s not quite true. Although some of the 65 presentations probably wouldn’t have made the grade at Sydney’s Fashion Week, several young designers stood out.

Sofia Kokosalaki‘s bold print dresses with fine curlicue straps and tooled leather detailing have marked out an aesthetic that, although a little too close this season to Nicholas Ghesquiere’s Balenciaga silhouette, augur well for the future. (As one local shrugged, “It could’ve shown in Paris and people wouldn’t have laughed.”) Persistent rumours tie Kokosalaki to an eventual deal with Fendi, in which case another bird flies the coop.

“Yes, I saw several good ideas, but they don’t necessarily translate well into clothing,” complained iconic Paris buyer, Maria Luisa, as she swooshed back on the Eurostar with her order book almost empty. “I’m always out to discover the new, the next thing, but this season London was very disappointing.”

And the English know it. Going to London Fashion Week this season was like popping in unannounced for dinner and finding the family quietly eating Spam instead of sirloin (the usual red-faced greeting from many of my dear colleagues, in fact, was “Oh my god, what are you doing here?”

It’s the British press that is left to bark up what Coleridge notes is a pound stg. 14 billion industry employing 270,000 people. But is the fashion journalist’s role that of cultural and industry critic? Or simply a spruiker, shouting out loud to get the shoppers attention no matter what’s for sale?

Murdoch and Mel in movie marriage

Sen. John Warner / Elizabeth Taylor
Sydney. Two of the country’s best-known expatriates, Mr Rupert Murdoch and the actor Mel Gibson, have forged an alliance that could see local film producers and actors achieving fame and fortune without leaving Australia. Fox Filmed Entertainment, a division of Mr Murdoch’s News Corporation, yesterday announced a three-year partnership with Gibson’s Icon Productions to produce and distribute films in Australia.

The chairman and chief executive officer of Fox Filmed Entertainment, Mr Peter Chernin, said he wanted the partnership to become an “aggressive and adventurous” player in what he regarded as one of the most exciting film production centres of the world. “We are also really aggressive about looking to develop the next generation of talent,” he said. “I think that is really what this venture is about, more than anything else. ”

The venture will be headed by a leading local film producer, Mr Timothy White, who produced Spotswood and Death in Brunswick. But it will remain in the development stage until Mr White has finished work on Gillian Armstrong’s adaptation of Peter Carey’s Booker prize-winning novel, Oscar and Lucinda, at the start of next year.

The president of Icon, Mr Bruce Davey, said Gibson’s involvement in the project would be significant. “If the Icon label is going on something, Mel is going to have some sort of involvement in it,” said Mr Davey, who was born in Australia but is now based in Los Angeles.

“He actively gets involved in script development, choices of direction, casting, whatever, and I would expect that to continue.”

Mr Chernin said the companies’ previously successful collaboration on Braveheart, which won last year’s Oscar for best film, provided the impetus to launch the long-term partnership.

“We have been partners and pals once before, and when that movie ends up being not only one of the biggest international box office successes of the year, but also wins the academy award, you sort of go, maybe this is something good here, maybe we should keep this up.”

Mr Chernin said they had not yet decided whether the projects would be primarily low-budget films, like most Australian productions, or big-budget ones, like most Hollywood productions. But the general view was that most of the movies were likely to be more modest in scale.

“I think one of the things we have endeavored to do is not put any sort of box around this, other than to say we want to make terrific movies, and anything that we think is economically viable, whether it is a small movie or a large movie, we are sort of up for it,” he said.

While the production company would be based at Fox Studios at Sydney’s Showgrounds, Mr Chernin said there would be no pressure to use the facilities. “We think there is an opportunity, but there is no obligation on the part of this venture to shoot films there,” he said.

Putting a new label on a national icon? So, wattle they think of next?

A threat to change the name of one of our most important genera was, thankfully, thwarted, reports Diana Snape. THE world of botany rarely invokes images of cloak-and-dagger tactics. This year it came close, when Acacia, the name of one of our two biggest and most important plant genera, was threatened with change. Acacia was originally thought to be one genus of about 1300 species, 1000 in Australia, the remaining 300 in the Americas, tropical and South Africa and tropical Asia.

Lucinda Williams
Recent scientific studies by botanists worldwide showed that it should be divided into three genera. Racosperma was chosen for the Australian genus, Senegalia for the other and Acacia remained the third. The accepted practice is that the first acacia named, an African one, would keep its name as the type species. However, exceptions are made and impartial botanists thought there was a strong case for changing the type to an Australian species, Acacia penninervis (Hickory wattle).

With its 1000 species, Acacia is by far our biggest genus, ahead of eucalyptus. The number of species in Africa is only 79. In Australia, the multibillion-dollar agroforestry industry and the massive horticultural industry would be affected by the name change. Confusion would reign.

Think about the millions of plants in botanic gardens, herbariums and nurseries to be relabelled, not to mention the scientific papers, reports, articles, books and photographic collections that would need to be changed. Many endangered acacia species are part of local and national legislation.

The proposal to change the type to an Australian species went first to the wonderfully named international Committee for Spermatophyta where it was fiercely opposed by those with African and other interests.

Eventually the vote resulted in a 60 per cent majority. This recommendation went to the general committee, normally a rubber-stamping operation. The conflict continued and the result was close but a pass. Finally, nomenclaturists met at the International Botanical Congress, held in Vienna in July. Two hundred botanists hotly debated the general committee’s recommendation.

Lobbying was rife and the outcome uncertain. Two hundred and fifty letters from Australians at universities, botanical institutions, conservation groups and concerned individuals helped by supporting acacia as part of our national psyche, with Wattle Day and our national colours of green and gold. The final result? Acacia was saved for Australia – but only just.

  • They are very effective in removing particles which are very minute i.e 0.01 microns.
  • It can efficiently sterilize bacteria, smoke and other variety of toxic fumes.
  • As no fans are required for their functioning so there is very less noise made by them.

Cons of Ionic Purifiers: Though these particle are very effective in cleaning air to the microscopic level but still lags in few places.

  • The particles which got removed from the air get settled down on the floor or rooms.
