Having experienced your exact problem, and not possessing the "plywood"
sized
router bits, I've been very happy with the router jig
http://www.rockler.com/ecom7/product...rings_id=10482 -
manufactured by Accurate Woodworking Tools
http://www.accuratewoodtools.com/. It
automatically sizes the dados to the exact thickness of the plywood (or
other
stock) that you have, using a standard 1/4" or 1/2" router bit.

No connection to either company, just a satisfied woodworker.

Well, that's all well and good, if all of your pieces are the same size (but
just not all 1/2" or 15/32" or whatever). When you're making a cabinet,
it's really tedious if all your dadoes have to be sized individually.
