Okay, so I've got a design that I'm ready to commit to wood, at least as a half-scale lauan toss-together to see if I have this lofting and plate expansion thing worked out.

So, the exercise is one of taking hundreds of x-y points, plotting them onto a big old piece of ply, connecting the dots with a batten, and taking saw to wood. The last two are decent ways to spend an evening. Plotting all those points sounds like considerably less fun, and a challenge to do accurately. I'm seriously considering the purchase of some Lee Valley bench tapes to stick directly to the ply to aid in the process, and probably another to add to the edge of a shop-made T-square.

Any other ideas to ease this step would be greatly appreciated.

Dan.
