Chipmaster Lathe Polyvee belt Conversion

[Alan JacksonParticipant @alanjackson47790]

I have been wondering for some time if I could replace the toothed belt drive with a Polyvee belt drive with the object of making the lathe run quieter. The problem is to get the belt to fit without much slack as there is no adjustment. Well I did the sums and the plan was to press aluminium grooved sleeves over the existing toothed pulleys. Well luck was on my side and it has worked out very well and is considerably quieter. The toothed belt gave a whine varying from a loud wasp buzz to a high pitched scream, but now that is completely gone its like a different machine.

Brilliant job, Alan

Makes me really wish I had made room for a Chipmaster.
