Just wanted to pass on a cheap solution I found this weekend.
Just about to drill the horns on the elevators where they attach to each other via the HS bearing and needed a guide to fit inside the bearing and protect it while drilling the pilot hole in the elevator horns.
Found a nylon spacer at Ace (aviation dept of course) for $0.17. 3/4 inch long, OD 1/4, with ID .115 if I remember correct. Bought a pair of 7/64 (.109) bits and was OTD for 4 dollars even. The spacer fits TIGHT in the bearing, is long enough, and the bits fit with no play. Haven't used it yet but looks good so far.
PS, would have bought a proper drill guide but didn't want to wait for shipping.
