First off, sorry I meant to put this on the chainsaw forum. JPS, if you wouldn't mind please move this. I only want to try square ground on my PP7900. Another forum member was kind enough to grind me several to get me started. I'm just trying to see how much more perfomance I can get from the PP7900.
You can look at it here and from there call Dan Henry his handle here is DozerDan "Paid Sponser" He is working with Silvey right now so he could most likely give you a better price and save you on the shipping.
good move.. i get the round file sharpening dn,, an now i send my chain off tobe sharpened.. its just faster..
one thing i dont see is the tendency to get dull faster,, that i was expectin. holds edge as well as round to me.jmo
