Pinbock thickness

[David Renaud]

The original pins were only 2 1/4 inches with
only 1"3/8ths of pin actually in the block.

Open faced block inserts through top of plate(router job and fussy
fitting)
, so no extra pin height required to clear the plate.
So if I use the same size pin I am safe with a 1"1/2 inch block.
The only concern so far assume problems with cheating on
pins depth but this is not the case. I can go with original size pins.

I thought a potential problem would be reducing contact with the
flange but the distance from the top of the block to the bottom
of the flange is 1 1/2 inches.

I'm not sure why they went with such a thick block except that
they had insert cut outs into the plate, and wanted extra, so ordered
thick stuff. But they did not take advantage of the depth with longer
pins.
