[AT] Chain saw sharpening

[Len Rugen]

If you have a Dremel tool, they make a saw sharpening attachment.  I 
have one, but I don't use it unless I hit a rock or something.  A file 
and guide work.  The guide just controls the depth of the cut, it rides 
on top of the teeth, it keeps the right "hook" on the teeth.  You hove 
to hold the file flat and at the right angle.  The trick is when the 
chain just starts to dull, stop and sharpen it.  It should want to cut, 
if you're pushing the saw into the cut, it's dull.  I use the 
"dangerous" full chisel chain for clean work.  I think a saw that works 
without fatigue is safer.  For fencing and brush work, where I will get 
in the dirt, the round chain will last longer.
