Grinding stones for sanding.

[greatdane2]

I bought a Foredom tool last year and it works great for shaping small parts. I use carbide bits to rough out the shape I want and it is so fast and easy. But right now I am making a Santa Paws set with 9 great Danes with antlers pulling a sleigh. Roughing out the antlers after compound cutting went well until i got close to what I wanted. The bits are so agresive that I ruined most of the 15 pairs I cut out. I am using Western Red Cedar and the antlers are about 3/16" at the base and using sanding paper wood works but not very well, to many angles to get to.
Anyway the point here was I tried a couple of grinding stones that I thought were for metal. and poof they work, very well. I had thought they would jam up like sand paper does. Not so, they work well and just take of a little bit off at a time and gives me the control I need. This is probablly old hat to a lot of you guys, but for me it was a last resort before I took a hammer to 2 days work. So in the morning its back to the scroll saw to start some new ones.
Hope this saves someone the agro I have been going through.
Does anyone know how to shape these grinding stones? I know you can get tools to true up normal grinding wheels. I was thinking about trying to use a lathe file and see what happens. Any ideas would help.

G'day Alan,
Try running your stones on another stone. For example and old oil stone. That should shape them.

Ok will try that, thanks John

My old dremel kit had a chunk of silicon carbide for dressing the wheels.
John's suggestion is good one, just don't use your good grinding wheels.

I was told that under no circumstance shoud you use wood on a metal grinding stone. It has something to do with the wheel exploding . Not sure how the smaller dremel stones would be affected ? Would one of those star wheels used for truing up larger grinding wheels work ?
