Cabin frame deburring
In addition to some fun Father’s Day stuff (walking in the park, swimming, playing croquet), I spent a few hours deburring and countersinking the last few parts on the cabin frame. I just need to paint the parts and then rivet the support to the cabin frame and F-706 bulkhead. I might leave some of that riveting for later so that I can remove the cabin frame for better wiring access.
As I mentioned before, the blind countersunk rivets have a slightly larger head than the solid rivets. I didn’t countersink deep enough for that, so the heads were sticking up a tiny bit. I used the Scotch-brite wheel and some sand paper to take care of that minor problem.
I also did some dimpling and riveting at the top of the F-706 bulkhead. The plans have you leave out some rivets at the top of the bulkhead. However, with the new cabin frame attachment those rivets can be set.
