I just bought a Bench Dog 40-123 Pro plate to fit into an old used Bench Dog cabinet. It is predrilled for my new Triton Plunge Router. So I don't have to drill the template. However, it does not have a hole for the table winder hand which raises and lowers the height of the router. That was disappointing. So if I want to use it, I have to drill the hole for the handle. The 40-123 came with no markings or any idea of the material it's made out of. I want to drill the hole but I'm not sure about how to go about it. Does anyone have experience with this 40-123 plate?
