What is the size, speed and make of the grinder did you use to get the result shown in the photo you attached to post #53? I have a 4 1/2" grinder that goes 11,000 rpm. Surely that can't be the right thing. Is the set-up something like what I see in the photo in post #49? What about this adapter that is comes as part of the jestco kit? Do I need it? Did you finish with a Cyclo or was it grinder all the way? Any and all help on this will be appreciated.
