I finally found the time to finish up a rear mounted Sherline cutoff tool holder as per Mikey's writeup and plan that he posted over on www.machinistblog.com back in 2012. It's great! My experiences with the stock Sherline cutoff tool contain enough surprises that I found myself approaching every cutoff operation with some trepidation. Mikey's tool is lots easier to set up and cuts at higher speeds with no problems at all. More rigidity, easier oiling, etc. I haven't seen or used Sherline's rear mount version, and I won't because this one exceeds my expectations. Thanks, Mike.
