I decided to make up some zero clearance inserts (ZCI) for my Grizzly table saw. I am using some phenolic resin that I got from @sawman101 (Bruce).
I cut strips to width on the table saw, cut curves over sized on the bandsaw and used a flush trim bit on the router. Drilled a finger hole and rounded over all the edges with a small router clamped in a vice upside down.
I drilled and tapped some holes for 1/4-20 set screws for leveling.
A few observations:
Cutting a 1/2" hole in the phenolic resin took more effort that I expected on the drill press.
Tapping the holes has also been a bit of a challenge. The resin seems to melt a bit and gum up the tap. I can get "ok" results, but not great.
It will be nice to have the inserts handy when I need/want them and not worry about it costing you $40 a pop.
