I just want to thank anyone and everyone ahead of time for the help. So I built a belt grinder for making knives at home in the garage. I was able to find a free treadmill and I am using that to power my belt grinder. There are way too many unneeded pieces and sensors and so forth. I just would like to be able to turn it on and increase or decrease the speed that is it. I don't want to know what my heart rate is or how fast it's going or anything else just the basic on and off and speed control.
