I needed some inserts for my “new” (1968) 20″ Rockwell bandsaw. I had some squares of Corian countertop material sitting around, and it was just right.
I turned the inserts to the correct size, being careful about the diameter and thickness so they would sit just right in the saw table.
After cutting a slot for the blade, I marked where the slot in the table was, and super-glued a tab there to keep the insert aligned.
The one insert with the round hole is for wet wood, to help the chips clear through the table and (hopefully) get to the dust collector.
