I ordered a narrow size range of pj-section belts to determine the best size for the auxiliary bench grinder drive I had just built. V-belt Guys' price made them the best option for this purpose. I'm not impressed by their products' quality tho. They're cut wiggly and run rough. Now that I know the size I'll be seeking better quality elsewhere.
