Neat trick, Ed.
I think I can do something similar without drilling a hole.
Bend a wire. Hook it under the bottom end of the mast in the
rotor. Pull it taut. Bend it against the outside wall.
Withdraw it. The distance between bends should be the wall
thickness, shouldn't it?
Thanks for the clue, though. I'll try it at the top when we get
up there with the bucket to take down the A3S.
