I recently picked up a face plate for a D1-5 mount that fits my lathe, but it was missing the mounting studs. I also acquired a 8 inch D1-5 adapter plate with studs that I plan to use to mount a four jaw chuck. My question is this: The D1-4 mounts seem to have only 3 studs, while the D1-5 mount have 6 studs. The size of the D1-5 is 3/4 while the D1-4 is 5/8 of an inch. Would it be a problem to use just three studs on the face plate and three studs on the chuck adapter? Chuck size would be 8 inch and the face plate is 11 inch. I guess my question is more are there any safety concerns with this plans?
Thanks
Mike
