Sharpen Your Own Chainsaw Chains

Do you have a chainsaw that isn’t cutting like it should? Is it creating sawdust instead of nice little wood chips?  Maybe its time to have your chain sharpened. Now the question is, do you pay someone to sharpen your chain or do you sharpen it yourself

Who Needs A Chainsaw Chain Sharpener?

My thoughts on this are there are three categories of chainsaw owners, each having different needs.  No matter what category you’re in a chain sharpener can be a handy tool for anyone.  What you’re willing to pay may vary though.  Read on to see what some of your options are.

  • The first is the infrequent user. This user may use their chainsaw just a few time a year. They may cut up tree branches, that have fallen in their yard, or cut some bonfire wood. This user may use a file to touch their chain up occasionally and have it sharpened by someone once a year.
  • At the other end of the spectrum is someone who has a firewood or brush cutting business. These users may require sharpening multiple chains on a weekly basis. Its probably more cost effective for them to spend the money on a high-quality electric sharpener.
  • Then there is the group that falls somewhere in the middle. I consider myself in that category. I cut between 25 and 30 face cord of firewood a year. This requires sharpening my two chains somewhere between 10 and 15 times a year. That’s beside touching them up with a chainsaw file between sharpenings. For someone in this group, I would definitely recommend purchasing a less expensive type of electric sharpener.  They can do you a good job for several years

A Chainsaw Chain Sharpener Can Save You Money!

The higher quality sharpeners offer more precise and accurate sharpening, but most of them will cost you hundreds of dollars. However, many of the less expensive sharpeners can provide good service at a much lower.  I purchased my sharpener for about $30, five years ago. In that time I’ve sharpened the chains I’ve owned at least 45 or 55 times. That would have represented a cost of approximately $225 – $275 if I would have had someone sharpen them for me! There was also the convenience of being able to sharpen my chains whenever I needed to.  There are times when that is a huge benefit!

Benefits of Electric Sharpeners

When you sharpen your chainsaw, it is very important to sharpen all the teeth equally. This keeps the saw cutting nice and straight. That is why an electric sharpener works so well. Once you get the sharpener adjusted to clean up the first tooth, the rest of them on that side are sharpened equally. Then switch the angle to the other side and sharpen the teeth on that side.

Possible Downside of Less Expensive Sharpeners

Chain in sharpenerThe only downside I’ve experienced, with a less expensive model, was the accuracy of the sharpener. When I switch from the teeth on one side, to the other side, they were not perfectly equal. You would grind more off one side, and that’s a no-no!  On the more expensive sharpeners, the angles are the same and should be for the price you are paying for them. By being uneven this causes you to spend a little more time making adjustments to sharpen both sides equally. It still only takes about 15 minutes to sharpen a chain.  To me, it’s worth the time.

This doesn’t mean every brand of chain sharpener that cost less than $50 will have this problem, but if it does, all is not lost. When the time comes to replace my sharpener, I will be looking for another $30 sharpener, similar to this one. If you know of a good quality, accurate sharpener, for less than $50, please leave a comment and share it with the readers.  That would be the best of both worlds!!

The Work-Around

After sharpening the teeth on one side of your chain, its time to change the angle to sharpen the teeth on the other side.  This is where you need to take care when using a sharpener that may have accuracy issues. Just like when starting the first side, carefully make an adjustment until the tooth is cleaned up.  Now continue sharpening the rest of the teeth on that side and you’re all done!

Chainsaw Chain Sharpening Tips

First and foremost, always wear safety glasses when running any power tool, especially a grinder of any kind.  I would also recommend wearing earplugs as well.  Please consider reading my article on safety for home projects.  It has lots of good ideas.  Before beginning to sharpen your chain, mark one tooth with a marker or some paint, so you can identify your starting point. Then when making the initial adjustments, I darken the first tooth’s cutting surface with a black magic marker. This allows you to clearly see that the entire cutting surface has been cleaned up. This is a little trick I learned back when I worked in a machine shop, running a surface grinder.

If you hit an object while using your chainsaw, like a nail or a rock, you may need to go around the chain a couple of time to clean the teeth up. In this case, don’t try to grind it all in one pass. Go around once, then adjust it to take a little more and go around again. In most cases going around once will do the job.  A set of calipers is a good tool to help keep the teeth even from side to side when using sharpeners with accuracy issues, or when you use a manual sharpener.
