So finish up plowing a bunch of dominos in a Cabinet I was making. I am a big fan of the Seneca Domiplate and as I was removing the thumb screws to remove the Domiplate I noticed as I was unscrewing one of thumb screw is became harder and harder to unscrew it. I had to put some channel locks of the screw to remove it. When I finally removed the Domiplate I noticed something had worked it's way out of the hole - it looked like a helicoil was inserted into the hole so screws can tread into the hole. So I grabbed it with some pliers and it came right out without really trying too hard. Anybody else experience this with their Domino???
