Reply:Not hard at all if you take your time, prep it properly and clean it. Again, if the above is adhered to, it will hold forever.

Reply:Yes you can.  Clean it thoroughly.  Don't use abrasives with aluminum oxide in them.A trick I learned here is to go over the piece with the torch and no filler.  This will float some of the crap to the top so you can clean it again.  It also preheats the piece.Here is a golf cart clutchhttp://www.weldingweb.com/vbb/showthread.php?t=15798Real world weldin.  When I grow up I want to be a tig weldor.
