Well, as some of you know, nothing dulls a chain saw chain like frozen wood. I have two saws, that the chains are getting pretty dull. I have been feild sharping them with a file, but looks like they are due for a REAL sharping. What do you guy that cut wood al the time do? Sould I replace the chain, get the equpment to do it myself, or send them out to be done? Where is a good place to get chain? anything on the web? If I send them out, who does this kind of work? Thanks for any help. My workhorse saw, an old Homelite superXLauto with a 20" bar is the worse. Starting to vear a bit when cuting. Guess I am not that good at sharping them.
