Go to Race Saws and you will find threads where people have modified Stihl or Oregon bench mount hand grinders to file square chain. I plan to do it but haven't put the time or effort into it yet.
Which bench mount you got? I have the FG-2 and reading the manual, you just get the Stihl square files, set your angles and sharpen. The only thing that has kept me from trying is you have to buy 12 files at a time in the pack @80.
