Have you asked your Amish supplier how much they would charge to supply
the
blocks already to your spec?

If you are not part of the solution, you are not dissolved in the solvent.


Well, kinda'! The idea was brought up but dismissed due to the fact that
the slot has to be indexed to one end of the block. The tolerance is +/-
1/16" and if the block is but in the brush machine the wrong way, and the
block was over or undersized, by even the 1/16", the pattern would interfere
with the mounting holes. The clamps on the brush machine leave a witness
mark that orients it in all the rest of the operations. However, I intend
to revisit it now that you bring it up. If the Amish can mark the
orientation, it'll work. Good idea, thanks!
