Seems like no matter how many times I filed this tool rest I was never happy with it when using my big bowl scrapper on edge for a shear scrape on the interior sides of bowls. Having just gotten the 9" Robust tool rest and falling in love with it I stole their idea of using a piece of drill rod glued to the edge of the rest. My what a difference that piece of rod made for me. Skew edge or scrapper either one now glide over that edge just as smooth as can be, I used extra strength epoxy from the borg to attach...Bill...
