Tom, if you have a dremel, pick up a set of these buffs and try them on a rule or a bit. I think you'll like doing it this way a lot better. I used my cordless dremel.

Timbeal, I believe Jim R. ID'd it for me as a Snell. I'm sure gonna try it the next chance I get to cut a mortise. I used the Millers Falls in my last class and like it alot. I'm not expecting this one to be quite as nice (no depth stop or reverse of the rack). I'll have to rig up a depth stop for sure.
