OK guys & gals,
I was out in the shop tonight ( imagine that) and am taking a short break before heading back out to clean up some more. ( decided the dust rhinos on the bench were a bit rude).
While I was out there, I measured the hole I'm going to fill with my router extension, and for fun checked my piece of countertop which i've used to 'glue up' the cutting boards on, etc... Lo and behold it almost Exactly matches the dimensions (20"x27") only missing by 1/16 on the long, and about 1/2" on the short dimensions. That's 'fine' as far as I've been planning on a hardwood 'edge' to make attaching to the TS easier, so a little small is fine.
This is a former countertop scrap which I picked up last year sometime. and is typical formica over particleboard. short of buying a pack of confirmat screws, what would you recommend to connect the hardwood to the particleboard?
At this point I'm planning on making a rabbet in the hardwood to support the extension on three sides (front back and where it attaches to the cast iron web/wing.) TIA for any/all advice. Now back to getting dusty cleaning.
