Ah- I know that the CSs are generally brazed in first, but wasn`t quite sure why. Thanks for the explanation. Like you noted, this frame is a bit funky, with 12 in. "seat stays" and 37 in. "chain stays". I thought it would be silly to do the long ones first because they would be too wobbly out at the end of that long span. As soon as I stick the short ones to the back of the main tube, it`ll be self supporting and the alignment ought to stay put much better while I prep the long ones.
