I didn't want to say anything as you are doing a cracking job on your build, however if i had to bore a pulley i would have set it up in a 4 Jaw with 4 short pieces of silver steel inserted into the belt slots and clocked on the OD of the pins then it's spot on with the newly bored hole. however if you don't have a 4 Jaw this isn't an option.

Hi Mike
I welcome suggestions on other ways to do things so please do mention them. I've only had the lathe a year or so and still lots to learn. I do have a 4 jaw chuck and it takes a bit of time to swap over (retaining nuts are a bit fiddly to access) but I like your idea. Pity I've just bored out the ones for the X axis so they are all done! Next time though . . .
