Grinding Rocks

[nkbj]

Those shaft mounted conical grinding rocks that are so very handy for touching up revolver chambers and coning muzzles, found them for $1.49 a package!

Where?

Are they intended to be mounted in the chuck of a power drill? Sounds like a recipe for really buggering something up to me. I'll mount a bore brush in a drill chuck to clean insides of suppository gun cylinders, but wouldn't dare use a grinder on a finished part.

You can use them with pencil grinders or electric drills or a drill press if such would suit the job at hand. Found these here in Indiana. The last batch I found for a good price was years ago while running through Idaho.

Geez! Those things would scare the _______ out of me mounted in ANY hand held power tool and used in any stage close to final!

Another reason to be VERY VERY careful when buying a used gun.
