My belts are trashed and have no more spare belts. I am looking for the correct O ring sizes that work on the SL. I found several post that show the following sizes but i would like clarification on which exactly work.
Here is what I found.
#331 for the smaller
#342 for the larger belt.
OR
Large drive belt #340
Small drive belt #332
OR
The sizes range for the Large Belt #340 to #342
And #331 to #332 for the small belt.

Power Feed #336
So which ones work best?
 
I use round urethane belting on my Levin and Derbyshire lathes. This stuff is better than O-rings for use as a lathe belt. Learn to weld it with a hot piece of sheet metal and cut the flash with a nail trimmer.

PS: Do not mention that small Austrian lathe on this board. The site owner has forbidden it and will lock your thread. Emco Maximats are OK to mention.
