More to it than lots of layers. In my cabinet shop we prefer to use plywood on a domestic core. The imported Chinese birch plywood has lots of layers, but it twists and bows all over the place. Best place to shop for quality plywood is some place that supplies the cabinet trade.

Bill....The SwitchMaster linkage can handle thicknesses of most any amount. All that is needed is to use a brass tube cut to a longer length. You could have five inches of thickness and it would not matter one whit. The piano wire rotates within the brass tube and so the thickness is not a factor with this linkage. No need for a slot at all. Just a small hole. > I just got a 2 HP plunge router. All you need is a 1/8" drill and some brass tube of the correct diameter. Have you considered a jackhammer? > Is there a 5/8 plywood? Yes. And I have used it all over the Mighty NYC mainline where the riser/supports are about 18" apart so that my shoulders could fit in between. For the yards, I used 1/2" plywood with joists spaced about 14" apart. Works fine if you use good quality (lots of layers) plywood. Beware of cheap plywood. There is a big difference between the good stuff and the horrible stuff. > Thank You, > Bill Lane You are welcome...Ed L.
