That sounds like a plan. I'm wondering if that same method would work for a homemade table saw insert. One of the most difficult things I have found to do is get a table saw insert flush with the top of the table saw. And when I do, if I remove it, and later use it again, it seems it is on longer flush and I have to go through the process again. Same thing with the boughten inserts. Yes I clean the accumulated sawdust out of the hole.
