Phil, I will go to Woodcraft and pick up a 15/16 and an 11/16 Forstner bit. After the job you can have the bits, those are both an odd size. The 11/16 is for the Conduit.
There is no Dyhedral but the Cabin Top Plywood Airfoil ribs will taper in slightly near the back of the Fuse. These two Pieces can be drilled 1" to allow for the difference and I can make a Ply doubler with a 15/16 hole to glue after final positioning. I left you a text, I am availible today, I will go to Woodcraft this morning. If you want to go with me Call and I will buy you lunch.

P.S. I know what you mean about that Woodcraft store, went there the other day. Plenty of tools there that would improve my Craftmanship.
