I'm looking for a n40 spindle speed increaser for my shizuka 3 axi mill. Somewhere between 20000 rpm at least to 40000 rpm or more. I've been to ebay and a few other places and the prices just is to much. If anyone has one they don't need thats willing to part with it for a good deal , you'd be giving it to someone thats going to put it to good use. I figured I'd try this, if not I'll just have to stick to my 3400-4000 rpm speeding galaphagoes tortis. Thanks
