Hi Nick,
    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.

Hi
Ron: Using Stainless
steel, it's a very good idea.Have
you ask the PSN group about using wood for parts in sensor? Should be interesting
what some comments would be. 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.) Nick

 Hi Nick,
    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.
