Huge campy dropouts. Also, jig questions.
So I have these gigantic campy track ends (as attached). The tabs on them are massive, and I'd like to convert some high-end road frames to track using these drop outs.
My question is, are they usually filed down to meet the frame? Do I file them beforehand? Should I just leave them?
Also, Anvil makes a great dummy axle for brazing these. What other types of small jig solutions would you recommend? I could easily just use an old axle and level the dropouts so they're parallel, but neither to dummy axle nor my axle would insure that the insertion depth of the dropout (into the chainstay) would be even. Any ideas?
