I'm thinking of learning how to braze and am thinking of doing a rack as my first project. I searched around and found a few good sites by people that have done this. Now I am at the point of chosing materials. I can't decide on stainless or4130 steel.
As I do not wish to spend too much money before I know if I will graduate to bigger projects, I will probably start with a couple small bottles of MAPP gas and a torch head. I'll get a decent bender and files. I have clamps, etc already.
What thickness of material (cromo and stainless) would be recommended for a small front rack to support 6-12 bottles of beer? I've seen that people recommend 4130 in either 3/8 X .035 or 3/8 X .028 and I've also seen 5/16 X .035 . What tubing is close in strength in stainless and can it be brazed with MAPP?
Finally, if I were to choose stainless, what grade would be ideal for an unpainted rack? 304? 316?
Thanks very much!
