Thanks Mason. Dan sent me a sweet looking square chain, but I want to save it for some cleaner logs. That's a loop of RS that's getting right to the sweet spot. Only a few millimeters left before the witness marks. They always seem to cut nice once you get there. I usually only run 20" bars on 70+cc saws, so I like rakers pretty low. I sold my tree monkey 455 this spring to help buy a truck. Truck fell through, so I bought one of
@Homelite410's excellent chain vises as a consolation prize. That and a bright headlamp really make freehand filing a much more pleasant and effective job.
