Yesterday I was lucky enough to pick up a Foley Belsaw automatic saw sharpener, a retoother, and an automatic setter. All for $150!
The only problem I have found is that the nylon drive wheel on the retoother was dry rotted, fell apart when I tried to use it. I am able to manually spin the flywheel and retooth a saw so it's still fun to play with.
I have a couple old saws that are truly goners as far as being functional. I am using these to play with until I am sure I won't mess up a good saw.
