I didn't see any problem with using wood, as long as it didn't warp. It's all older dry wood, and been clear coated.
There is a lot that I'm doing different in this design, including the transmitter / receiver design, detector (which I plan to build myself), and how the force feedback works. I haven't done anything more than rough sketches, which change as I find out what material I can scrouge up to build it. When its finished, and if it works well, it will have the Shackleford-Gundersen form, but will have some significant differences with respect to how it works.
If we could send image files to the list, I'd post a few rough sketches for comments.
Thanks for your interest.

Will you be building the Electronics for the detector your self. Do you have plans for the Receiver and Transmitter ( Not sure if that is the correct name for those parts.)

nice job on your detector. I've been making mine out of wood, it is only my first attempt at building one. For the hinge at the top, I plan to use stainless steel foil that was originally used as the recording medium (analog form, the data was scribed onto the foil). I'm not sure what the thickness is, but a 200 ft spool of it is less than 3 inches in diameter.
