This worked out really well for a first attempt, I've been wanting to try this for ages to stop belt slippage on pulleys and drive wheels when running accessories off steam engines under load which can very often be a problem as some engines lack the power to be able to put a lot of tension on a small round drive belt.
It’s a great hobby and pastime working on your metal lathe or metal milling machine making parts for model engines and model or toy steam engines.

That really looks like it came out perfect!
I noticed that you ran it around the pulley many times. Were you advancing the carriage or cross slide a few thousands with every revolution, as you were continuing to cut?

Yes Daniel every second revolution around 2 thou.
I'm really happy how well this method worked and how relatively simple it was using a tap in the 3 jaw chuck. I made up some more different sized jigs and hobbed some more ali ad brass drive wheels yesterday afternoon.
Nice work Jim!
Thanks Charlie appreciated mate.
Here's some photos of a vertical transmission that I made some years ago that I have 'retrohobbed' one side of the drive pulleys on this morning.

Very good stuff. I bet it grabs the belt way better. If you have a powerful engine and lots of accessories this is a must.
