Drilling For Rocket City Type Control Horns
What is the best way to drill ailerons , elevators ,etc. for the 8-32 Rocket City type control horn bolts so they are perpendicular to the control surface centerline. Do you shim them up in a drill press to get them exactly right or ? THANKS

If you are using foam sheeted wings and surfaces,
use the shuck and masking tape to hold the flying surface to the shuck
Accurately mark your hardpoint(dowel)
Drill
If you don't have shucks, shim the flying surface up so the drill will drill straight.

I usually predrill my hardpoints before I install them in the wing or tail core. A V block stood on end helps to keep the dowel centered on the bit. Use a forstner bit or a piece of sharpened brass tubing to drill the dowel hole in the surface. Keep the surface taped to the shuck while you are drilling. If the hole in the surface is not perfect don't worry about it you can fill in any voids with epoxy and microballoons. You can also adjust the dowel to ensure that the horn bolt is properly aligned.
