I am building my first frame. (4130 cromo, lugged) My original plan was mapp gas and 56% silver filler. Now I have an O/A rig and am wondering if I should stick with silver or go to brass. Is the O/A to hot for silver or would it be easier and more idiot proof b/c of the lower melting point? Also, if brass is the way is there anything wrong with the flux coated rods which I happen to have a wealth of or should I go with bare rods. I will of course be using paste flux as well either way.(I'm not that big an idiot)
Any and all advice will be greatly appreciated.
