Today I test fit the aft bottom skin, aft bulkhead, and tail wheel mount. The bottom skin cutout was pretty close, needing just a small enlargement to clear the tail wheel mount. The aft bulkhead needs a bit trim so the skin and contact the bulkhead flanges, and the weld bead can clear the bulkhead. I spent a couple of hours assembling, disassembling, trimming and repeating before it started to fit well. I still have some more work to go before this is final.

I will need to use some shims to close the gap between bulkhead and mount. Right now the gap is large, almost 1/8th of an inch. This is in part due to the weld pushing on the aft bulkhead, keeping these apart. Will be interesting to see how many shims/spacers I’ll be up needing here.
