I need to make a couple new zero clearance inserts for my table saw. I have a new router table that I figured would help, but I’m having some problems with end grain that didn’t come up when I used to make these inserts with the router in hand.
I traced the old template, then cut it out very close to the line with my scroll saw. I’m cutting these out of some oak that was lying around, and I was worried from the get go about the end grain on the radius. Using a pattern following bit to finish the job and taking light passes, everything went smoothly along the edge grain. As I got to the curve on the end, the first half of the curve cut well where the blades cut away. But, predictably, as I turned back around the curve, the blades were then digging into the grain and the router threw the piece out of my hands, chewing up the end.
I’m using a 1/2” diameter bit at full speed on a bosch router. I’m not climb cutting. I don’t have a fence or balance point on my router table yet—could they help some how? I know for square ends a backer board would be the solution, but I can’t really do that on this curve. I’m thinking I should cut all the safe parts, then flip the wood to finish it off. Any other solutions for this kind of work?
Any recommended books for Router Table uses/jigs/safety?
