Butt weld clamps are good for keeping this gap and keeping the panels flat. Also another note when you are sanding if you see your steel is turning blue then stop immediately, the metal is getting too thin. Flap disc are great for finishing welds I wouldn't use a grinding stone for one reason and that's because they produce heat which can be controlled if you don't stay in one spot too long, goes for the flap disk too. You want long strokes when you grind and you want the abrasive as flat on the material as possible this will prevent you from digging into and gouging the material. If you need any advice on welding I'm a good guy to ask I do it for a living haha good luck with the project!

Thanks for the tips. I am using a Lincoln electric Mig Pak with no gas... it works "okay" for sheetmetal but, I wouldnt use it on anything thicker... I really need to upgrade but, I dont have a clue where to go from here. I would love to learn how to TiG but, a TiG set up isnt cheap. I definately need to upgrade to a gas MiG soon - Especially if I go forward with bagging it. ...and to be honest, I just love to weld. Its thereputic! LOL
