Where do I find a chuck like this?

[TonyBen]

Or do I have to make one? What kind of chuck is this called?

I think it is called a spider. I have one on the back end of the spindle bore of my lathe.

You will have to supply the backplate that it bolts to Grizzly sells those as well
You could make one as well but probably not for the asking price.

You can make one for 5 bucks . A piece of thick wall tubing with 4 threaded holes . Mount in your 3 or 4 jaw chuck . This is a simple tool and project . Make one for the rear of the spindle also . Great for gun work .

You see that at the other end of spindle.
I think look for a 4 jaw chuck.

Yep that will work for a d1-6 spindle

Thanks all! Mine is a D1-4 (according to the Precision Matthews website for my lathe model- 1236T)

This issue with the premade spider is the mounting bolts get into the pull studs on the D1-4 spindle. Here's how I did mine. I used 6" aluminum so I could use set screws and not have the bolt head protruding from the spider and potentially smacking your knuckles.
Bought a thick back plate https://www.grizzly.com/products/south-bend-8-1-4-d1-4-back-plate-thick/sb1396 and made a small counterbore to help locate the aluminum plate after I turned the OD.



With a 6" plate and thick backplate, you can space the mounting bolts out far enough to clear the pull studs on the spindle.


I used an 8" backplate to give me a handle to grab and rotate the spindle by hand. I did the same thing with my receiver spider.

Thanks for all the info!
