Any ideas are welcome. I just finished builded a grinder off the NWG plans and I can not get a belt to run on it. Every time I start the grinder it throws the belt left or right off the rollers. I check the drive shaft and it is square with the base. I pulled the tracking wheel and replaced with a 12" piece of all thread to verify it is parallel with the drive shaft. It is within 1/64" of parallel. I pulled the platen off and ran it slack belt with no change. The tracking wheel is from Beaumont so I know it is good. The drive wheel is from McMaster Carr and is fairly soft. I had it tracking for 30 seconds or so and when I restarted it i thrusts the belt away from the grinder on restart. I increased the spring tension and it seemed to get worse. I had a single spring 8" long and 1" in diameter. I changed it to a standard door spring with no change and tried both springs.
