The other thing to watch for is the bar wearing unevenly from side to side.
This will make cuts go off a straight line and start to curve.
Also watch for 'bluing', the discoloration of the bar because of
overheating caused by underoiling.

Dean,

When the bottom of the chain hits the bottom of the bar channel or the two
channels on the bar wear down allowing the chain to ride not touching the
bar then its time to get a new one. Can't say by time wise because it
depends on friction, proper use of oil, etc. A worn bar will cause the
chain to go bad quicker.

Not sure how long a bar should last. I've sharpened the chains many
times now and it seems great. Just wondering how long bars last and how
it will show itself. Thanks!
