I have a Grizzly G4000 that has 39mm x 4mm threads on the headstock spindle. I also have several tools and chucks with 1" x 8tpi threads and have searched high and low and no one has an adapter. Lots of 33mm x 3.5mm adapters but no 39mm!
My question, does anone have any idea who might carry a 39mm x 4mm to 1" x 8tpi adapter? Grizzly is closed 'till monday, MSC is offline, KBC, Little Machine Shop have nothing and my Google searches are coming up empty handed.
If I can't find one, I think my only solution would be to insert a mt-3 spindle with a 1" x 8 tpi end and use a drawbar to hold it in.
