2 x 72 New !
Just taking possession of my new big boy grinder. 2HP with a VFD. Since I never had a variable speed before what do you who operate these run the speeds at for a.) stock removal (I am working on post heat treat blades in high carbon) and the b.) finishing. Also for the finishing belts, do you run those backwards? And also at what speed.
90-100% until you get the blade thinned down. Then I'll progressively slow the speed with each progressively higher belt grit. For blending and fine tuning things I run it at about 65.
I don't run anything backwards except for if/when I'm sharpening blades on the grinder.
Thanks for your advice.
