"SteveB" fired this volley in
:

I'm using a chain saw more now. I got four or five chains, some dull,
and some unfindable. I have a Sears sharpener that has an alignment
jig. I have kind of gotten the hang of it, and it seems to work
pretty good. But, we're going to go up and cut some wood, and I think
if I can figger out the angles, a pocket hand file would be infinitely
easier to use in the field.

The trick the old loggers around here use is not to sharpen the chain,
but to _keep_ it sharp. "Sharpening" involves more than just putting new
edges on the teeth, you also have to grind/file the gauges to keep the
penetration depth correct.

The old guys just use a file in the field -- a new, clean, sharp one.
Most of them own a real chain grinding rig for the evening 'true' re-
sharpenings. Y'know; one of those things that looks like a compound
cutoff saw with an abrasive disk in place of the blade.

'course... these guys also buy chain by the roll.
