How have you all managed to open up the tooling holes for conduit or snap bushings? With my unibit I can reach all ribs except number 2 & 3 (the two most inner on the wing walk). The unibits I have go up to 1/2" and 3/4" and the drill bit extensions all have at least a 0.6" head to them.
So far I've drilled the holes up to 1/2" (would like 5/8") using the unibit and 12" 1/2" drill bit (worked fairly well). I installed snap bushings with 3/8" ID. However I'd like to take the holes bigger but I can't come up with a tooling solution.
The other thought I had was to make another set of 1/2" holes for another set of snap bushings. These wings are getting pretty busy with pitot heat, nav/strobes, pitot/aoa lines, and autopilot! What have you all done about getting the holes bigger in a QB wing?
Thanks,
Scott
