Is there a hole like a normal lug so the down tube butts against the head tube, or will it butt against the head tube lug surface? The first is a lot more work, the second little lighter.

Speaking of which, have you considered clamping the lug tube around its future tube mate and then mitering them at the same time?


I love the fact that brass and silver brazing temp differences makes this possible. It is too bad bronze and stainless mix poorly - those would be neat looking bare lugs for little cost.
