I’ve been offered an old Hall Toledo EJ. Does anyone have a source for valve seat grinding stones? I’ve tried some of the majors: Regis, Cylinder HS, Goodman etc. without success. The company still has a working website but I can’t get a response from them. Thanks
 
Andy from Hall Toledo finally got back to me. He left me a voicemail and apologized for the delayed response. He said messages from hotmail accounts have been going to their spam/junk folder. He also confirmed that they still carry the stones and dressing points. Russ, Goodman doesn’t carry anything that would work out of the box with this machine. I suppose It may be possible to adapt something but I don’t have it in my possession at this point and frankly I’ve got too many other projects going on to spend time machining parts for it.
 
The hall Toledo has different threads and mounting than other systems, it works differently than other systems too, the stone only contacts a small area an a eccentric changes the stones centerline
 
What size & thread pitch are they. I have an Australian made Repco”Warren Brown “ seat refacing set but have not found an US made stones that fit.
Thanks
