would you suggest 3/4 of 1 1/2 inch spacer as i was going to laminate 2 pieces of 3/4 of plywood together and then start cutting from there.
heck they sell wood ones

Since you're a woodworker I'm guessing you're going to use a veneer plywood.
No voids with this stuff and it should work ok.

A couple pieces of laminated oak strike me as being a good way to go as well.
Orient the grain 90 degrees to resist warpage and use an epoxy glue.

Another option is to use UHMW.
It's a white plastic that is very strong - about 70% stronger than the Teflon it resembles.
Easy to work with, the only difficulty is getting a smooth edge, but the right sander should take care of that.
