Is there a chuck?

[Greylights]

I have a 4 jaw headstock chuck with a threaded female hole M33 3.5 on the front and was wondering if there was such a thing as an adjustable jaw chuck that would screw into it to hold various tools, such as a pen mandrel. Looked on Amazon and eBay but frankly I get lost. Any ideas will be much appreciated.

A picture of this odd device?

Just hold whatever you want to in the jaws, reversing them if possible to get longer gripping surface

Pen mandrels often come on a morse taper I think, just take the chuck off and use the mandrel direct in the spindle morse taper, assuming it has one of course but most lathes do

That's a metalworking chuck which is why I couldn't quite visualise it. As above - pen mandrels have morse tapers, put them straight in the headstock. Beware if you buy a mandrel from China - they tend to be 6mm not 1/4", so most of our suppliers bushes and spacers don't quite fit.

Brilliant. Thanks.

Thanks for all the advice.

Don't try gripping tapers though.
