I've had a lot of problems trying to drill the holes for the aileron LE skin to the aileron counterweight pipe. First I tried drilling through both simultaneously. The holes in the pipe came out OK, but hte holes in the sking became severely elongated. Then I tried adding some new holes in the skin, marking and using a center-punch to mark the holes in the pipe. Then I tried drilling the holes in the water pipe separately. When I put it back together I found the holes in the water pipe didn't line-up with the holes in the skin. I think the drill bit keeps slipping on the surface of the pipe getting hte holes out of position.
Even using my drill press, the drill bit itself flexes causing the hole to move.
Any suggestions?? I've already written-off at least one aileron LE skin.
