Wing tube drill jig


Wing tube drill jig
I need to drill some wing tube holes for some TWF wings, and I need to dial in as much dihedral as I can get between the top skin and bottom skin over 5 or 6 inch wing tube....so I made up this little wing tube drill jig.

It allows me to set the root entry point (wing in the bed), and then the maximum dihedral (wing out of the bed, extend drill tube until it just touches the bottom bed).

Materials used for Wing Tube Drill Jig:

- 3/8" brass tube (for 11/32 wing tube for 5/16 wing rod)
- Two 1/4"-20 brass button head machine screws + nuts + washers
- 8"chunk of 1X3 poplar
- Two chunks of a wood yard stick

Materials used for Sub-Rib Drill:

- 1/2" Copper Pipe Repair Coupler
- 1/4" Piano wire for handle

Nope, just used a dremel and a sand drum to shape the bolt heads to conform and then just silver soldered them using paste flux......I tried to break em off by hand and couldn't do it....so they're pretty strong.

Since the photo, I cut the tube length a little so that my 11/32 drill reaches through so that I can drill the root rib when it's in place.

Putting that mini-mill to work.....very cool........not that HD yard sticks aren't cool, but machined aluminum is cool.

Got to say Dan good design. I cut 4 pairs of spar tubes holes perfectly and quickly.
