What size D1 camlock adapter has 4 locks

Camlock adapter?

Camlocks have only three or six pins or locks.

If you have a set of calipers, measure either the external size of the pins or the inside diameter of the pin hole. Pin size will be able to tell what size it is.

Camlocks have only three or six pins or locks.

This is why I ask my 6" 3 jaw chuck has 4 camlocks, I have a 4 jaw I would to put on my lathe but can't find a faceplate that accepts the 4 camlocks.

How about a picture. That seems odd.

I'll see what I can do tomorrow

You probably don't have a D1 camlock. As ddickey said, D1 cam locks either have 3 pins (D1-3 & D1-4) or 6 pins (D1-5 to D1-11). Unless someone removed 2 pins but that would be pretty obvious. Never heard or anyone removing 2 pins though, have only seen people remove 3 of 6.

What lathe do you have?

For quick measurement of chuck mounting dimensions, measure from center of spindle to center of pin, “D”.

Possibly a proprietary chuck mount. Make and model of lathe and pics would help immensely.
