Brief Description: Wing rigging - day three
|
|
On to drilling the forward spars. I had already match drilled the spar blocks out to 3/8" before I built the wings. I used Hugh Beckhams's pilot drill bits. Thanks again Hugh! So, my procedure was to first drill the forward attach angles directly to 3/8". For the rear attach angles, it looked impossibly tight to back drill the rear attach angles. Instead, I used a 3/8" transfer punch to mark the aft tunnel web. I then removed the web, re-cleco'd the vertical angle and gusset, and very carefully drilled it out to 3/8" on a drill press. It all pinned together fine -- a major milestone -- and a nice way to start the new year. With the flying surfaces, fuselage, and canopy complete, I'm feeling that the major milestones are behind me, and that I'll finish #583 this year. Now it's time to remove the wings, put everything back in the workshop, and final rivet the spar tunnel.

Phew! The pin fits perfectly!

It's really starting to look like a plane.
