You appear to have a D1-3 or D1-4 headstock (they both have 3 pins). You can find out which by measuring the centre to centre distance between the pins. All of the dimensions are easily found in charts online.

You can then order a collet chick that will fit your headstock.

So D1-4 headstock it appears. Now to move onto what backplate to order....

Now to move onto what backplate to order....

?? didn't you determine that you have a D1-4 spindle? A set thru type collet chuck will come with the back plate. The cam studs and locking screws will be packaged with the chuck. Screw the cam studs in to match your other chuck positions. Test the pullup on the spindle. Adjust if required and put the locking screws in. Doesn't take long.

Yes, finally took time to confirm the D1-4 size. Thanks for the directions on what's next.

So I found this collet chuck on Ebay but am not finding anything about the pin sizing elsewhere online. Any thoughts or ideas?
