I can't believe there isn't more dremel users out there !!!!! Maybe I'm missing something here , kind of why I wanted to see what everyone was using . In my younger days I used a file and hated it , I had a old Oregon file holder and that was it, . I thought it was very time consuming and didn't enjoy it at all . When I got my OWB and got back into cutting I now owned a dremel and figured I wasn't going back to hand filing ever again ,BUT lately my chains just don't seem to cut as good as they should , don't get me wrong they cut pretty good but it seems like I need to put more force on the saw to get the speed I want .The saw isn't pulling itself into the log . I'm going to try sharpening one of my newer chains free hand with a nice new file and see what happens !! Any tips welcome.
