Bar grinding-make your bars last longer and cut straight for $10

Grinding your saw's bar to keep it cutting straight and vastly
extend it's life is something people overlook. As a mechanic in
a shop it's a job I would perform at any tune-up or servicing of
any saw. Keeping the rails of the bar true will keep if from
wearing faster and only takes minutes to do. If you have access
to a tablesaw you only need to purchase a $10 metal cutting disc
from a hardware store( 7" diameter,1/8" thick with a 5/8"
hole),then you will be able to grind and true all the bars you
want for many years,and probably not need to buy new bars
anymore.
Install the metal cutting disc in the tablesaw,then using a
square adjust the disc so it is exactly 90 degrees(lining up
with the square),using the adjustment wheel on the side of the
tablesaw. Put on a safety face-shield and leather gloves and
start the tablesaw,now you want to be grinding the bar about 1-2
inches from the outside edge of the disc,you can see by where
the sparks are. First pass grind lightly starting where the
bartip meets the bar, then slowly and steadily push the bar all
the way through all the way and around the "tail" of the
bar,then do the other side. Now inspect each side of the bar and
you will immediately see where all the most wear is. Now make
more passes until you've ground the worn areas away and the
rails are now,flat,square and true. Clean the grooves and blow
them out with air and grease the tip,good as new.
Warning- You only need to exert light pressure to grind the
bar,but it is possible for someone to push the bar very hard
into the disc causing it to break and fly apart. I've been doing
it for 20 years without a problem,but for extra safety you can
make a steel or aluminum disc to fit behind the cutting disc for
extra safety,even a smaller diameter saw blade behind it would
work.
Saw shops charge $10 to $20 to grind a bar,and many of them are
not set accurately at 90 degrees ever,so not always very
accurate or true.
Bars can be ground over and over many times,a real money saver
for people running long expensive bars.

I got a question maybe someone can answer. I just fixed a 590
Jonsered and a Homelite super 2. The Homie has no chain brake
and the 590 brake band is broken.
The owner no longer has a job due to his employer going out of
business and he says he doesn't have much money to spend.
I'm spooked with a liability lawsuit in case he or someone else
cuts themselves with one of these saws.
Any thoughts?

I would give the customer a receipt disclaiming your liability
if they injure themselves and have them sign it, if something
about the machine is unsafe.

Frankly a chainsaw can be a very dangerous tool if used
improperly. Recently I watched someone on Youtube falling
trees,I couldn't figure out wtf he was doing,cutting through the
hinge etc.,finally the 3rd tree rotated on the stump and fell
butt first on his saw putting it out of it's misery and ending
his suicide falling.

The grinding disc I have now I bought about 20 years ago,it's
still in great shape,it's paid for itself a hundred times at
least $$,now that I'm retired I service all my friends bars with
it in exchange for favors.
I'm guessing a lot of saw shops today do not have a bar
grinder,better to sell a $100 bar than make $10 grinding one
back to new condition.

Thanks Mike, still a grey area with him signing something that I
wrote up. I'd probably need a waiver written up by a lawyer.
What I"m going to do is unfix the Homie and hold onto the 590
and order a brake band for it. # is 503 45 97-01. No Jonsered
dealer here . Does Husky have this band on one of their older
saws?
Good idea with the table saw grinding wheel BTW1

Have a standard work order made and have a lawyer write the
disclaimer,I never hesitated to scrawl a disclaimer across a
work order,or simply refuse to fix something I knew could be
unsafe or dangerous.

Seems like I remember somebody posted a Husky 55 band would
work. IDK personally.

A lot of their parts are interchangeable,even have same part
numbers.
