Today I laid up F28 and the longerons. I did these two first because I don’t have enough BID to do any of the other bulkheads. Also, I’m going to vacuum bag most of the bulkheads, and since this one is small I could do it without giving up much weight. It’s also not particularly visible in the finished plane, so I felt like if I made a mess of it with my first layup of the plane, I wouldn’t see it in the end.
With the longeron, I found it really easy to hold against the jigs. some other builders had mentioned needing multiple clamps, but mine only needed the two pictured here. I also put a few weights (buckets of concrete) to hold the plywood flat. I put a few screws in to hold the longerons in place, but in the end they weren’t necessary.
Here’s the longerons:
And here’s F28:
