If you do much fabricating, you'll be amazed at how much quicker it will be to clean up and remove stock. After I finished mine, I kicked myself for not having one long ago. Bench grinders, even 1 HP units are no match for these machines. I was afraid the belts would be expensive and always needing replacement but found out that is not the case.
I use good coarse belts and remove the tension as much as I remember to.
