Michael, that is a great idea.
Actually, we use this method at work to open up dowel holes that are too tight. I just figured it would be better with the right drums seeing as I have the whole kit. Seems the old principle of KISS (Keep It Simple, Stupid)

is still the best sometimes.
The coarse ones on the drums work very well for removing material and shaping things up. You need to get a diameter as close to the radius you are working as possible. I guess if you do not have the right diameter drum you could make one out of a round piece of wood. Drill a hole through the centre and put a bolt through with which to clamp it in the drill chuck and either use your slit idea or the tape idea. I will try the tape out today.
Thanks for the good ideas.:thumbup: I am sure you have helped a lot of other folks too.
Rob, that is just terrible. I will NOT buy anything from these guys!

Being left out in the cold can just totally demoralize guys and make them give up. I know how hard it was to get started here, if it was not for this forum and some very decent individuals I might have given up when I started, fortunately quitting was just not an option for me, it became personal.
Anyhow, you might not realize it but you are filling in a lot of those gaps in Canada. Your name is getting out there, keep it up, we need a good supplier up here.:thumbup:
Thanks to All,
Mike
