A new fixture

I got fed-up with putting down tube shifter bosses on by eye, so today I cooked up a fixture. It's inspired by the head set press that comes in a Campagnolo tool kit. I already had the rod & cones, so I just had the fabricate the other components.

 

Hey, do any of you have an actual dimension for the optimal location of the bosses relative to the intersection of the head tube and down tube?
