You can make a quick bore clamp from the type of wall bolt fixing that pulls a wedge up between two jaws with some plastic wrapped round for protection.
Print a linear scale of the required number of ticks and wrap it around the circumference of a ply disc turned to size.

Loads of references to dividing in the forum you just need to try all sorts of search words.

Bazyles post of the linear strip has been used for X number of years and is hard to beat for results and effort to make if you dont think you will do this sort of job again.

The Quorn is yet another one of my unfinished symphonies but I accepted at the time of its commencement that it would test, almost to destruction, the extent of my very limited toolmaking and workshop skills. In the years preceding buying the castings I discovered the pleasure making and using well-designed attachments for the Myford lathe, notably those of Jack Radford. His head-stock dividing attachment (only suitable for the Super 7 & ML 7R), his graduating device and his spherical turning tool all proved their worth when making Quorn components. GHT enhanced and ‘corrected’ some of Radford’s ‘faults’, there is an error in his worm data for the headstock attachment for example. I think your time would be well-spent making some of these type of attachments, which will then be available to make your life easier for all future projects, before commencing your Quorn instead of looking for ‘quick-fixes’, although I understand the enthusiasm for wanting to ‘get on with the job’. For me, it was all good toolmaking practice and I learnt a lot in the process the results of which have shown up, hopefully, in the Quorn components I have thus far made.

Simon,

As far as I can see, you haven’t said which lathe you have, but if it’s of any use or gives you food for thoiught, I offer my take on it.

It’s was a progression from my simple indexing feature in MEW some while ago, further explored in my low-profile rotary table.  It consists of an annular ring which slips over the chuck and is secured thereto. Another ring, drilled at 10° intervals around the outside is overlayed by a segment plate, drilled at 11° intervals.  More complicated than is is, actually.  A picture paints a thousand words and a video or two even more, so …..

It used to be in an album, now drifting in the multiverse, but a video to watch is here on YouTube.

It effectively gives you the equivalent of 360 holes drilled radially in the chuck backplate, indexed by a pin of some sort.

P.S.  I no longer possess the lathe, this accessory or the 3D router it was made on, or I would offer to make one for you.
