Nutplates

Tonight I installed the nut plates onto the bulkhead parts that make up the aft wall of the baggage compartment. It was trivial, but a little tight around the flanges. I managed ok with my hand squeezer in the vice.

With the hand squeezer in the bench vice, I was able to squeeze all the rivets for these nutplates

Primed pushrods and bulkhead

I’ve been busy with work and family stuff, and have had several weeks without any airplane time. Today was warm and dry, so I took the chance to prime a few parts. I made a custom stand for the pushrods since they are cylindrical and had openings at each end that I didn’t want to prime (they are already primed). Everything came out looking ok.

The threads are plugged with silicone plugs I bought when powder coating the pitot mast. Nails through a block of 2×4 at each end allow the rods to stay up off the bench, and they can rotate freely.

Bulkhead test-fit

Today I dimpled, drilled, and test fit the baggage compartment aft wall bulkhead. Dimpling was tricky in places due to the flange shapes, but I managed with my hand squeezer and narrow dimple dies. I step drilled a systems hole, and then started test fitting the bulkhead. I’ll need to flute the flanges, but ran out of time tonight to finish.

Bulkhead

I’ve done about as much as I can on the wings before I have a tech inspection, so I started on the fuselage tonight. There are a few rivets I need to set, but I went out of order and started work deburring the bulkhead that forms the back of the baggage area. I decided to get these parts ready to prime, so I can prime the aileron pushrods and these parts together. Not much to report; I finished deburring two of the three parts.
