I guess I should chime in here as I am partly to blame for the box of spar caps. They were newly manufactured about two years ago by our shop. Don't worry, we had lots of help. The material for the outer spar caps is 2024 T3 that is 16ft in length. It took us most of a year just to find the material. It's .375 thick on the outer caps(upper and lower) and .250 (?) on the inner caps. The material had to be cut to width, machined with tapers, then formed to shape and finally profiled in width. The shape is not exactly the final shape of the spar as CV in their wisdom used clamping pressure and the bending load of the caps to close some of the gaps. They also used a lot of shims. We had enough material for seven spars when we combined our new material with what we have salvaged from other spars/wrecks. Right now we are assembling the fourth and last spar for our projects. A fifth one will be disassembled, repaired with new caps and reassembled. What's left over is available to the highest bidder I suppose.
John Lane is working on outer wing panels (several). He is a great resource but was not involved in the spar project. I'm not aware of anyone else doing this.
One last comment, I cannot conceive of a more difficult and complex design for an airplane. But, on the same token you'll never see one break.

Hi Lynn.... sorry I didn't credit you guys properly with the spars... the poster on that site seemed to intimate that John Lane had done the work. I know that he replaced the spar caps on the Brian Reynolds corsair, and was assuming he'd done the same for you... so was it the other way around? Which corsairs are you working on, by the way? Also... I assume that the spar marked with F2G is from Dave Etchell's corsair... what was wrong with it? It looked really nice in the photos, although there did appear to be some gouges out near the end in one of the photos from what looks like a grinding wheel. Great to hear of the work you guys are doing!
Cheers,
Richard
