Since its beginnings as the British Welding Research Association in 1946, TWI has been at the forefront of arc welding development.
Our achievements include developing carbon dioxide shielding for MIG/MAG welding, making the process viable for welding carbon steel, and building the first solid-state power sources, paving the way for thyristor and inverter technology.
With a team of 21 welding professionals, including seven highly qualified International Welding Engineers, the AWE team at TWI is qualified and experienced to provide expert guidance on any issue relating to the welding and joining of materials.

Being Expertly TIG welded along the whole edge means the fender will need absolutley no body fill or work of any kind - there is no reason to cover up good welding like this. Straight to the powder coater as is.

£1.30 piece of welding glass taped to a Cokin 58mm adapter for a cheap alternative to an ND 110, a very reasonable £80 saving! Just testing in the garden before finding a better shot!

Added some shelves, with primary need being a place to store a rack of fire bricks for gas welding. Original construction here.

We continue to wrap up the rest of the chassis welding. If you haven't already seen, we just had the Rock Bug rolling for suspension clearance testing. This was blogged at blog.spidertrax.com/2009/01/07/a-rolling-rock-bug/
Glass and Cokin P adapter
Back a few weeks ago I started taking long exposure shots, some up to five minutes during mid day in sunlight. How is this done a few asked well you can run out and but the Lee Big Stopper 10 stop Neutral density filter. Just make sure your wallet is well packed or your credit card, average price just checked Vistek, $225.00, plus filter holder so by the time you are finished at least $300.00 taxes included. Now to me to pay that kind of money for something that may get used occasionally just didn’t seem right. My alternative after doing some reading was welding glass and it works, maybe not as perfect as the three hundred dollar filter but it works. Let me explain! First I bought three different grades of welding glass an eight a ten and a twelve. Now how to attach it to a lens, holding it in front of the lens was not a solution due to the length of exposure 30 seconds and more. So, I took a CokinP filter adapter as seen in the photos and glued it to the glass, super glue, then used electricians tape all around to eliminate light leakage. Now let’s add up cost so far $4.00 welding glass, Cokin adapter from Ebay average $8.00, Super Glue everyone has a bottle of this so 12 to maybe 20 dollars if you by the adapter at a camera shop.
Now screwing this rather large piece of glass to the front your lens really looks hacked, Rednecked, however you want to put it, but again it works. Now you will need your tripod and either a remote release or a cable release I prefer the cable as it allows me to switch on to open shutter off to end the exposure. So mount the camera on the tripod and compose and focus your shot, you will have to do this before mounting the welding glass as you cannot see though the glass to focus and compose, I will normally just set the lens to infinity. Now set shutter speed to bulb, aperture I usually start at F16. Ok, mount the welding glass onto your lens, attach your cable release or get your remote ready. Click your cable release or remote and hold for at least twenty seconds (this with a number eight glass) now a little tip put something over the viewfinder to eliminate light leakage and you will get leakage which will show as little flares. Now you have an image that is as green as the Green Giant himself, so now go to your white balance in your camera and adjust till the image looks close to proper on my Pentax K20D it’s around 2500 with a little tweaking from there. Now shooting raw which you should you can adjust the white balance in your Raw processor I find a good place to start is the tungsten setting and adjust from there, the other alternative convert to B&W which to me is the easy way out. Trial and error will get the white balance dead on see image below there’s two one with the welding glass one without.
This setup works well on waterfalls fountains, seashore with heavy waves, and on a busy street with people going by, for as long as they keep moving all you will get is either no people in the image or just some real ghosts. It is also fun to move the barrel on your zoom lens while the shutter is open, certainly creates a very neat effect. I have used both the ten and the twelve welding glass but prefer the eight.
In the picture you see my home made cable release which again I built for less than a tenth of what they wanted for the one with Pentax on it, if anyone is interested you can find the instructions here.

this is the one I used for my three Pentax cameras, K100D, K10D and K20D and it works fine
