I'm upgrading the Mini Lathes drive and electric at the moment. For the new motor I bought a pulley which I thought will fit to the old tooth belt. But it doesn't and instead the new drive runs incredible rough and rattles crazily.
For this reason I planned to change the drive to PolyV belt and pulleys as they run naturally smoother than tooth belts.
It isn't that easy to find the PolyV belts in this small sizes. First I preferred the smallest profile PH but this isn't available in the right size so I had to change to the next bigger PJ profile. For this I had to make two pulleys which I show in this video.

I hope you enjoy this little episode.
