brazing tolerances for practice work
My plan is to but some 1 1/8" 4130 with an I.D. of 1.009". I'd also get some 1" tubing. I'll be practicing brazing with 56% safety silv. I plan to cut rings of varying widths from the 1 1/8" tubing to braze onto the 1" to simulate lug work.
From my reading, lugs will be press fit with only a couple of thousandths tolerance. Will a nine thousandths tolerance be acceptable for practice work?
