I have previously suggested that free-hand filing chains is a lot like sex: a lot of guys probably think that they are better than they actually are. At the same time, enough must be
good enough that the world remains populated. And I have to assume that there are some Casanovas out there as well. I respect that there are different ways to get the job done.
A lot of the chains I get to sharpen are from guys who are not able to free-hand sharpen adequately over the complete life of the chain loop. I get left and right cutters grossly mismatched in length and angles. I get cutters that have hit rocks and debris, not necessarily out of neglect, but because we do a lot of storm / disaster clean up, which is harder on chains than cutting clean timber. For me, a chain grinder is the most efficient way to 'even out' those chains, and make them practically useful again, but not necessarily the best choice for
touching up an edge during the middle of the day.
You have to be consistent! that means every tooth gets the same number of rubs if the 1st cutter gets say 4 rubs all the cutters get 4 rubs! both sides no if or buts about it.
Agree on the consistency part: that is what filing and depth gauge guides are all about. They help to fix one or more of the parameters, allowing the user to focus on the remaining angles, contours, etc., and get more consistent cutters than by 'eyeballing'.
The problem with teaching people to count file strokes ('rubs') is that I see people apply different amounts of pressure with their Right and Left hands, and counting each as a 'stroke'. Or one stroke is counted with the file full of filings, and another right after it is cleaned. The cutters quickly become inconsistent. If each tooth gets 3 strokes, but one needs 4, it should get what it needs.
Again, I recognize that a skilled free-hand filer would produce more consistent file strokes.
Do you sharpen one or two handed? (hold the file) I sharpen one handed frees up the other hand to hold and steady the cutter its way more accurate and controlled filing IMHO im talking doing this on the saw sharping I've never taken a chain off to sharpen in my life a new chain goes on and only comes off when its done sharpened out.
I like the guide bar held solid in some type of vise, or groove cut in a log, so that I can control the file with both hands. Filing one handed seems a lot like shooting pool with one hand on the cue stick; just no way to keep it moving as straight. If the chain is off the saw, then I like a nice filing vise to hold the chain solid.
I take my bar off every day to clean it and clean behind it, so swapping chains is no bother for me. Takes seconds:
Just different ways of doing things.
