I am starting to mess with the Rocket city (or whatever) control
horns that come with the hardware kit. The kit has 6/32" button
head screws and lock nuts to be used as pins in the horns, but
the 1/8" holes in the rocket city horns are extremly tight on the
6/32" bolts.

A #29 drill bit seems to be a good choice for the holes, tight, but not
binding. Am I missing something here? I have never seen this
mentioned befor?

Another alternitive is to just run a 6/32 tap down the pin holes...
this may be a better solution since the 6/32" bolts have no shoulder
for the plastic to ride on.... the pivot point will be riding on threads as
it stands now?
