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.

How about a picture. That seems odd.

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?

Type D Camlock Mount



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


---------------------------------------------------
PIN
SPINDLE A B C D DIAM.
---------------------------------------------------
D1-3" 3-5/8 2.1250 7/16 1.391 .5937
D1-4" 4-5/8 2.5005 7/16 1.625 .6562
D1-5" 5-3/4 3.2505 1/2 2.0625 .78125
D1-6" 7-1/8 4.1880 9/16 2.625 .90625
D1-8" 8-7/8 5.50075 5/8 3.375 1.03125
D1-11" 11-3/4 5.75075 11/16 4.625 1.21875

Cheers

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

I bet you have a DIN 55027. Does it have a bayonet that you close then tighten the 4 nuts? That's the same as what I have and when I first saw it, I thought it was camlock.

The pins dia. measure .765 they look just like the pins in post #11 except there is 4 of them and are threaded for nuts, the lathe is a 13x40 Bolton. No bayonet but a knurled ring that twists to catch the nuts on the pins. I would like to know what it is so I could get a faceplate for the 4 jaw.

Those spindles are usually found on mini lathes & older import lathes. Unfortunately you may have a very hard time finding a backplate for it. I've never seen one for sale anywhere. People end up making their own.

Off the top of my head, Stefan's old lathe had this type of spindle. The old version PM1127 had it too.

I know Bison makes em but do you know anyone that actually carries them in stock & sells em? I had the same trouble when I searched for them. Well that was like 10 yrs ago & I don't want to be that guy who sounds negative. I suppose any distributor for those brands should be able to order them. Hope the OP is able to find one.

I feel like an idiot now after googling that number, Bayonet wasn't what I thought it was LOL. Looks like I'll be making it myself, Bison want's to sell me another chuck to go with it for 800 plus.
