Fabricated the HS Attach Support and Rudder Stops

I cut the horizontal stabilizer attach bar support angle from the provided aluminum angle. I measured it out with the calipers, marked it. Drilled stop holes in the inside corners and used the bandsaw to remove most of the material. I finished removing material with a vixen file and cleaned it up on the scotch brite wheel.

Made the rudder stops from the provided aluminum angle. I measured with calipers, marked up the angle and cut it on the band saw. I cleaned it up with a file and the scotch brite wheel.

I machine countersunk the top two holes in each rudder stop. I was totally stumped on how to countersink the other two holes on the inside of the angle. The countersink cage won’t fit. After some head-scratching I gave Jared a call to see what he did.

Apparently theres a thing called a “paint cutter arbor” that has the same threading as the countersink cage and one can mount the countersink cutter into it and mount it in the drill press. So I ordered one from Aircraft Spruce.
