I disagree the the although the photo is low quality teeth appear to have no set and are a shorter rounder tooth, the original photo has teeth that have a set and are pointed

Do a search for wood turning index wheel and there are quite a few from cheap to oh my prices. This wheel has all you need and more. https://chefwarekits.com/EZ-Index-Se...ing-p148000607
Sprocket and gears are other sources of ready made things you could scrounge up and use too.

The Aussaws blade a couple of posts above is a a metal cutting HSS coldsaw blade. I don't know the current cost (now retired) but a 300mm blank disk was in the order $135 plus cutting the teeth (typically $35) back in 2006 from our local saw guy, who was the BIL of the guy running Aussaw at the time. The blanks can be cut to virtually number of teeth required, depending on material being cut and material thickness. I suspect that you could be looking at $400-500 to buy a blank and get it ground to requirements these days, but haven't priced them lately.
If you can access a saw doc with an automatic sharpener for them, they should be able to divide and grind an old HSS or carbon steel blade to suit for the cost of the grinding, without needing to shell out for blanks.
I know you said your local saw doc departed a while ago, but most likely someone nearby will have picked up his customers if there are metal working shops, sawmills, joiners, or cabinet makers in the area. They all need a doc locally, or end up relying on posting or couriering blades out and getting them back the same way. I have some old HSS or carbon blades 175-250mm dia with 16mm bores, and could pack and post a couple for you if you can find someone to grind the existing teeth off and retooth to suit.I used to be an engineer, I'm not an engineer any more, but on the really good days I can remember when I was.

Thanks for the info Malb. I looked into those blades and immediately canned the idea due to cost.
I am currently working on a cheaper solution involving a cheaper blade with a suitable pawl to suit the the gullet shape, and it looks promising so far.
If it works out, I'll post a couple of pics. )

The outcome was good. The gullet in the saw blade has a 4mmD. semi circle in it, which engages very positively with the 4mm stud attached to the ratchet arrangement. (see pic 4)
My lead screw dial was never scribed very clearly, and as my eyes get older, it had become very difficult to read, so after making this saw blade indexer, I re-scribed the dial and it turned out better than I had hoped.

Glad you found a viable solution at a reasonable cost, do have anything for the other division rate you were interested in?
