Saw bars

When a bar with a fair amount of wear on it starts to make your saw cut crooked or otherwise poorly, do you just replace it or do you dress it (grind edges square and close the rails so the groove is the proper width)?

Is it worth it to dress them? Can dressing only be done with specialty tools?

It gets a little complicated. You can dress it, then check the groove depth to make sure the drive links do not scrape the bottom of the groove. Really worn bars are better replaced, because they wear the insides of the groove also, causing the saw chain to have allot of 'side to side' movement, resulting in a wider kerf cut. Which makes the motor work harder.

Pferd makes a tool specifically designed to dress bar rails.
 
I little tune up on the bar when it gets your attention is always great. But when wear starts getting significant, just scrap it. If its worn that bad, you'll have a hard time to get it to ever cut right on the money. Plus, a quality bar, if treated nicely, should last long enough that buying a new one wont be a thorn in your side.
Just my spin.
 
Try one of these, when you clean the bar check for a burr on the edge of the bar, if a burr is present then dress it.

I usually take the burrs off with a regular hand file.

What about squaring the rails? If you want it truly square, doesn't that take a machine?
 
You can square up a bar very nicely with a large belt sander.It can be done with a file but it takes longer .
 
And it works pretty well?

In the past I would bring bars that needed work to a saw shop and they took care of it nicely. But now there is no saw shop, just a lawnmower shop and they aren't into the finer details of saws.
 
Very well.

Universal Edge Sharpener & Replacement File

The unique Universal Edge Sharpener from PFERD is ideal for removing burrs, squaring and reconditioning your bar. Simply remove the chain and run the tool along the bar rails in easy forward strokes. A 90 degree angle is built in for bar truing. The replaceable file is cut on both sides for twice the life. When it becomes worn, simply open the unit and flip the file.

You shouldn't have to dress a bar very often.
Lots of chain lube, sharp chain and proper tension is the key.

I agree, probably once or maybe twice (not for burrs, but for squaring) and then toss the bar.

Where do I get one?
 
I inspect the bar every time I throw the chain (or when I change it) and dress it out real quick.
 
I have a little Poulan s-25 that I know has had at least a dozen-15 chains on it and several sprockets.Same old 14" hard nose bar it came with. Redressed many times.Shall we say it's getting a little pointy on the snout.
