Today I received a Granberg precision chainsaw grinder. The only thing I dislike is the lack of threaded 1/8" grinding stones. I found some for a dremel, but obviously this isn't threaded. Is there a way to adapt the granberg to a chuck style? I can't thread the 1/8" dremel stone because it's a smaller diameter shaft than the threaded stones. Any other thoughts on how to make these work together? If not, no big deal. I'm mainly trying to find an easier accurate way to sharpen my Stihl 1/4" picco chains. I am currently using my Granberg file-n-jig and it's pretty time consuming.
