The easiest thing for your band to do is raid the Quantico USMC Museum, jack their Triad off its supports and take it to Pax River where it belongs! Failing that, go there and look over their Triad. It is very well constructed, the just-completed restoration is superb, and the Museum staff and volunteers are a great bunch. You'll learn a lot and it is not that far from Lex-Park.
On this side of the mountains, I am relying on the Charles Schultz drawings as my primary source of construction details. These are the most complete drawings available, and you can build a faithful Curtiss Model D from them. I have augmented these details with close inspection of the USAF Museum Model D-IV in Dayton. The team which built that replica really did a magnificent job. It is very closely aligned with the Schultz plans. A close friend, Vet Thomas, of Rochester, NY, built a Schultz based replica a couple of years ago which now hangs in the airport at ROC. Vet did us all a major favor by putting almost all the metal parts and pieces on CAD. He can water-jet these out of 4130 plate in a matter of a week or so. He makes the turnbuckles, supplies the spoke nipples and bends the spokes for the turnbuckles. He also makes original style control pulleys and guards. I purchased a set from Vet, once I realized the enormity of the task of hand cutting and forming all the parts. Most, if not all, are interchangeable on the Triad. Still, you will have a lot of work left to make the parts fit. I have made changes from Schultz after comparing what I gleaned from my sources and from the advice of great people such as Vet, Art Wilder of the Curtiss Museum, Karl Ericsen from Owl's Head Transportation Museum in Maine and several associates on the Aerodrome.com forum. The info is out there, it just needs ferreting out. If I were a West Coast builder, the Hiller Museum and the San Diego Aerospace Museum are good sources and both have Pushers.
So, there are 2 Triads - at Quantico and at Hammondsport. It's worth the time looking them over.
