Re: Working on Frames Question
Excellent choice Tabogon!
I'm glad you looked into it more. An oxygen acetalyene rig is really the best, most versatile, set-up.
I am completely familiar with TIG, MIG, and Arc welding. I don't weld for a living: but I have done enough of it to be able to make nice welds using any method when I need to.
With this said; I still prefer brazing for thin materials.
As you discovered; brazed joints are very strong.
The problem I have with recommending MIG to someone who is inexperienced, (Brett I think you'll agree), is that it is very difficult to ensure that the weld has penetrated properly. A cold surface bead may appear as a nice weld, when in fact the two pieces aren't bonded at all.
With MIG everything happens fast...you "must" have prior experience in order to "know" that the joint is truly welded.
I would not be the least bit leary about riding a bike that had been built by creating fish mouth cuts at the joints, and then brazed.
