Caman: If you are just going to use this tool for buffing, or even grinding, why not have a tool for that purpose only. I have three 2 wheel grinders set up on a portable tool stand. One has 2 grades of wire wheels on it and I use it for roughing tubes or removing rust on antique tool I restore. Second has two different grinding wheels on it. It is used to sharpen tools and grinding metals. The last one has two buffing wheels on it, and is used to polish brass parts and pen blanks. The buffing grinder is an inexpensive one from Menard's Building Supply and was on sale for $29. I bought two 6" buffing wheels for $6 each. It has a 1/2 hp motor that turns at 3560 rpms with a 1/2 shaft. This also left me with 2 extra grinding wheels for my other grinders. I usualy polish my pens on the lathe after I finish them, but my son brought me one of his that needed to be repolished, and I didn't want to take it apart and remount it , so I bought the extra grinder. Now I don't have to remount any tooling on the lathe, just turn the switch on and go. Total cost $41. Jim S
