Burs on the bar

[CLIMBERJunkieee]

I got a problem. I work for an outfit here in the midwest and at my job im referred to the chain sharpener. I am the only guy that knows how to sharpen a chain on my crew. i use a round file with a guide. anyways i am wondering why burs keep forming on my bar and can that make it cut crooked? how can a prevent that?

Burs can form for a number of reason. Running a dull chain (which could be much of your cause with you being the only one that knows how to sharpen). Running the chain too tight can cause the bur as well, mainly along the flatter portions of the bar. Running a chain too loose will cause burs to form at the tip of the bar sometimes as well. Also running a cheap bar can cause this as well. I have noticed Oregon bars tend to bur easier than other brands.
Sure it can make the saw cut crooked, more than likely though uneven rails will cause this because the chain has rolled more bur off one side than the other.
There really is no preventing it, its gonna happen, steal on steal at that speed, somethings gotta give. You may be able to reduce the problem by addressing the cause. Hope this helps.

Get yourself a bar dresser. See attached. Keep your chains tensioned properly and Sharp and a good quality bar will outlast a cheap one by a long time.

When I am cutting a lot, I will go thru my bar once a week or maybe 2. A few minutes of maintenance here and there can go a long way to making your bar and chains last a lot longer. Oh, and teach those lowly greenhorns how to file!

I run a rail closer too. Take 3 links from a chain and use that to determine when the rail is cosed up enough but not too much. Then dress the bar. If you dress then close the flat surface the chain rides on will be out of square.
