The 6″ bench grinder at ENTS is finally going to get new bearings (the old ones have been screaming like a banshee on and off for 3 years or so), but SOMEONE *koffRichardkoff* mucked up the threads one end of the shaft. So, I chased the threads carefully on the lathe. Fortunately it’s the end with the right-hand threading, the lathe at ENTS cannot turn left-hand threads. Now we just need new bearings and it can go back together.
