I'm going to save this but here is a good reason to state the source URL. If I knew it I could go there and see the pictures the text refers to. Also Norm referred to a router collar in a recent show. I tried to buy one but they thought I wanted a collet. Does it have other names? It's a little bushing that fits into the hole in the base plate and holds the top of the bit from touching the wood. He used it to follow a pattern.
