I do use my dremmel grinder tip to grind down the depth gauge on my chains. I like throwing wood chips when I cut, not saw dust!I bought grinder tips for my dremmil. Sum bitches work pretty damn good! I would get them sharpened for $3, I just don’t think that far ahead.
Because I don't go through that much firewood at home I don't bother sharpening my chains. My Stihl chains last me several years.I quit sharpening my chains a long time ago.. For $3, my Stihl dealer sharpens them way sharper than I can get them, and I can have them resharpened quite a few times. Time is money, and not sharpening chains saves my delicate fingers.
