Drilling conduit holes in QB
I got this idea from some other website along the way. Not the only way to do this I'm sure.....might help.
My conduit tools photo.
I used the right angle drill for the open ribs and then the extensions for the ribs that are covered in the QB. First I made a template to mark where I wanted to drill the ribs then I started from the inboard end of the wing. The unibit that I have goes to 7/8 so I had to stop at every rib and remove the bit and put it back on the extension while still in the end of the wing. Real fun!  I made 3/4" holes. I'm using Van's flex conduit.

I'm then using RTV silicone at each rib to hopefully prevent vibration from causing holes in the conduit. The location for holes is suggested buy Vans in a pdf file here.
