When it gets bad enough it will tip over so bad that the saw will stop cutting. How old is you're bar? May 24, Click to expand Crofter Addicted to ArboristSite. Some good advice but some questionable too. Flipping the bar every time is no guarantee of evening out wear. If the bar was crooked when you flipped it, it will be crooked when you flip it back unless you dress it square in the mean time.
Maybe you need to clarify how the tips of the cutters get further apart when you file them back; unless I am confused, filing makes them each shorter but they all move rearward. Most of us are stronger on filing one side and so giving an even number of strokes to each cutter usually results in one sides cutters getting shorter than the other unless you use some method to compensate like grunting harder on your weak side.
Still you have to eyeball or measure cutter length on an ongoing basis and correct before it gets to far out of whack. I have seen guys go through the motions of sharpening a chain and not hold the file up enough to touch the edge of the top cutter at all. All they sharpened was the lower part of the side cutter and really it is only the top quarter of the side cutter and the top plate that does any work.
My guess is this is likely the cause of the crooked cutting iby the original poster. Crofter said:. Laughing, still dont agree on the increase of distance between cutters.
Yes if you shorten one cutter the distance from its tip to the one in front will be greater, BUT the distance to the one behind it will be less and the average will still be the same. The only way you can increase the average distance between cutters is to incur wear in the rivets. Anyways we agree that it is important to keep fairly equal lengths of cutter and raker, sharpness and shape side to side on the chain, and the bar rails square. Philbert Chainsaw Enthusiast.

Making one cutter shorter than another will result in a different measurement in the distance described. Traditional tool, imagine how much easier it is to put a chainsaw chain back in shape compared to all involved to do a real good job on a wonked up crosscut saw. My respect goes to the old woods man that could keep one of them cutting well and supply the power.
May 25, Couple of quick tips that may help 1. When sharpening the chain, place it in a vice which pinches the bar but allows free rotation of the chain. Rotate the chain with your file, not your fingers! Find the tooth in worst condition and file it untill it is sharp and count the strokes. Apply the same number of strokes to every other tooth. This will give you relatively even tooth wear for the life of the chain. As for future prevention, be more aware to do as good of a job on both of the sides.
You may even go as far as performing more strokes on one side, to compensate. The teeth have to be equally sharp on each end to make the chainsaw work straight. On that note, one of the best and easy to use chain sharpeners out there is the Stihl 2 in 1, which also works the depth gauges at the same time.
You can get one right from Amazon affiliate link. This can also be fixed by a proper sharpening session, though sometimes the damage done is just too severe and you have to get a new chain.
It is as simple as that. All cutter teeth should be sharp, filed at the correct angle, and be the same length. Usually this is easier to accomplish with a grinder than it is with a file.
When hand filing, this must be done by eye. On a grinder, the angle, depth, and length can all be preset. This makes it easier to duplicate each cutter tooth. When filing, it is more difficult. Those of us who are right-handed often do a good job sharpening the left side cutters, yet find in more difficult to sharpen those on the right side.
Those who are left-handed have the opposite experience. After several filings, a chain will usually show the effects of this. Teeth on the side easiest to file are usually sharper but shorter.
The other side has longer teeth, but may remain dull even after filing. People who use grinders are not immune to inaccuracy.
