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.

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.
