I used to polish hardened steel on my drill press using a small 1" homemade 1/8" shaft and 1" hard feldt pad and diamond paste. Worked pretty good, and I was sure to place the blade in a drill press vice. Yep, crude,dangerous,and hard on the drill press bearings. I didn't wait long to build buffers with yardsale motors! The only upside to the drill press deal was it was better than the dang Dremel!
