I use the red Fenner Power-Twist on my Metal and Wood lathes.

lasts and lasts. Intended for heavy duty use so light and medium
gives more lifetime.

I also use the Fenner belt material. You can get it on sale from Rockler
occasionally. Two things I've noticed:

1) Until they wear in, they generate a bit of red dust.

2) They can make an annoying zipping sound if the machine they are on is
quiet. It doesn't bother me on my bandsaw, but I took them off my Clausing
mill for that reason. It may also be a break-in issue, but the belt is
about at ear level, and I found it very obnoxious.
