I've been hand filing my chains this year, with great results. If your not doing this give it a try. What I need now is a saw vice to keep the saw stable as I'm filing the chain. What I do now is clamp the saws handle bottom into a saw horse type vice. It doesn't hold it very well. I was thinking of making something with clamps but........before this maybe there is something out there Any idea's and source for what I need?
