For the joiner plates and shoulder belt attachments I used a hydraulic jack on a fixture to bent the thick metal parts that I had made for a previous project. The hydraulic jack gave good precision and controllability.
I went for the join the forward fuselage to the aft upside down method as it was easy to setup supporting it on three sawhorses.
I checked and marked for how the fuel tank would fit fairly early since I wanted to get a head start on planning the firewall and behind fuel tank layouts. I also had to sit in it for the first time. A couple of sawhorses under the spar tunnel and seat channel with a plywood board between them gave me enough confidence to carefully climb in.
This is the drill I used for most of the build. It has a normal chuck as well but also came with an offset (shown) and right angle adapter which came in handy for one handed operation in tight areas. I also have the normal tight right angle adapter and long drill bits which are certainly required for some of the really tight corners.
