I'm upgrading my caliper brakes and long story short the mounting bolt needs to go into the fork at an angle (with spherical washers) in order for things to fit right.
The problem, of course, is that if it goes in at an angle then it doesn't line up with the hole in the rear of the fork crown. So I'll have to drill a new hole (which is no biggie since I'd need a new hole to convert to a recessed nut anyway), but I'm leary of being able to figure out the correct position and the hole is going to partially overlap with the existing one.
Soooo, I was thinking it might be better to put an 8mm slot so I can adjust the angle of the mounting bolt after. Will the lack of support from the slot compared to a hole be a problem or the oblique mounting be a problem? I think not because Sheldon has recommended mounting brakes without even any support in the rear of the fork and typically the curvature of older style forks doesn't really support a flat recessed nut squarely anyway, but I wanted to get some opinions here before destroying my fork.
