Measure once?

Okay, so I think I'm learning how to work with wood. Measure once, cut way outside the lines, and then sand it all down to fit. I think it would be easier if the plans had more than just the occasional measurement on the templates. To make things even more fun, the hull not only tapers from the middle to the front and back, it has a definite "V" shape from bottom to top. This combined with the guesswork on the templates is making it a bit of challenge to get everything to fit right. Here are some progress shots.

First up, the butterfly board. I don't know what else to call it, but this is what the chair sits back against on the top of the fuselage.

We'll skip ahead a bit. Here are most of the pieces ready for the first trial assembly. Yes, I had to throw a few out and start over once I realized they weren't going to fit during the test assembly.
