Alright guys I hope I don't open a big can of worms but here it goes....About 2 weeks ago I purchased a new Jet 1642EVS and couldn't wait to start turning. In the process, I purchased a new set of HSS turning tools then went on the internet and Sawmill Creek to look for ideas on keeping a sharp edge and grinding these tools properly. I found several people that said in old posts that a slow speed 6" grinder (one at about 1725 rpm's) was the best because you would not overheat the tool and they would last longer vs. taking them to a 8" grinder at 3450 rpm's. Then today the UPS man brought me my Oneway Wolverine setup to go along with my new slow speed 6" grinder and in the setup instuctions from Oneway they suggest you use a 8" grinder @ 3450 RPM's for best gringing results! Help! My head is spinning! Do I do what Oneway suggest, the 8" grinder at 3450 rpm's or woodworkingonline.com and go with 6" grinder at 1725 rpm's!
