“..filing by hand is the pros way to do it”
Real pros use a grinder. Preferably the Silvey. Not cheap, but made in the USA.
I can tell you firsthand that after a day of cutting on steep ground, running from yellow-jackets, dodging rattlers & widow-makers and driving 2 foot wedges the last thing a ‘real pro’ is going to do is spend 2-3 hours hand filing a 48” chain.
Believe me, I know these things.
I have seen that alot where a lumberjack spends an hour fiddling with the file and it still aint sharp or cuts in a circle
Watch out for the rattlesnakes, bears and widowmakers along the way
What I meant was a pro should know how to sharpen by hand, maybe they have battery powered sharpeners now that you can pack along. I know chain and bar sets sure are cheep now, compared to back when I was a pup doing forest work. So grind away and maybe the boss wont care about gobbling up chain, or if it takes some worker an hour maybe its cheaper to just let them grind.
I luv this thread , reminds me of the ones on the chainsaw forums LOL , (like an oil thread on a car forum)
