I have a jet 1014 lathe, which has an integral indexing feature. I know how to engage the pin, but it doesn't seem to hold itself in very well, and easily releases. I have read that it has 24 positions, but I dont know how to know which hole I am in at any time.

my vicmarc chuck has just arrived from Timberbits (great service!). It has an indexing back plate. I have no idea how to use this feature either! Do I need another item, such as a plate to attach to the lathe?

any pointers? It looks quite a useful feature to have, particularly for turning clocks with, or adding a small router to the lathe. I don't want to spend a fortune enabling it though.

Ideally a lathe with an indexing feature will have the divisions marked on the spindle somewhere. On my Axminster lathe they’re on the pulley. If your lathe doesn’t have any marks then you could try making them yourself.
For the chuck you’ll likely need to add a pin and lever somewhere on the lathe to engage with the chuck indents.

The indexing questions are valid and serious,searching on the net will yield concrete solutions as to alignment and pin condition of your existing lathe, and how to take full advantage of the back plate on your new Vicmarc Chuck. One negates the other unless there are more divisions on the chuck than the lathe stepping. The biggest mistake can be using the pin to lock the lathe when fitting chucks etc they shear off easily.
