I'm looking for 15mm belts / dressing / couplings for a flatbelt
Myford ML2 lathe.  Anyone know of a source?  Ideally near Bristol, or
else mail-order

Thanks

There's item 320269397229 on eBay.

You can always run a V belt on flat pulleys. The power rating may be a
little less but that may not be an issue on a Myford. It's accepted
practice to run a V belt on the larger pulley when the ratio exceeds a
certain figure. I can't remember the exact ratio but 4:1 sounds
familiar.

If you really must then try AC Belting. However the last maker of leather 
belts in the UK is now in Hungarian ownership and from them the minimum 
order is 5 belts. I had one via AC (who in fairness did warn me). It was 
crap and required me to sell a daughter.
I would urge you use the green stuff also from AC but cheaper and no 
stretch.
Alternatively try the last oak tannery in UK (Colyton Devon) who will 
probably sell you the leather very reasonably ( and a tour is well worth 
it).

I thought you couldn't do that on step pulleys though, as they tended
to wander?  Certainly I've never had any luck when I tried it. Non-
step pulleys are easy enough to convert to Vee.

I wonder if a polygroove might work even better?

You can use V belts on step pulleys. I had a lathe so equiped so time
ago. It helps if the "flat" pulley is crowned but that's not essential
if the other pulley is a normal V type.
My lathe had a flat stepped pulley as part of the headstock and
fitting a V belt meant a headstock strip down. The previous owner had
got around that by fitting a brammer type belt, the riveted type. That
meant the rivet heads were running on the flat pulley! It was noisy
and prone to slipping. A strip dpwn allowed me to fit a V belt, and a
spare was tied in place for later. Later I went to a twist together V
belt without rivets and that worked well.
I had a stepped V pulley driving the flat headstock pulley. As the V
pulley was narrower than the flat one, it was made to slide on the
shaft (it was an idler). That meant I could bet a wider range of
ratios by combining all the possibilities.
