There are a great deal of sharpeners obtainable, however for this technique, you’ll need a easy, cheap file and information set from Oregon. The set features a spherical file with a information, and a flat file and depth gauge. These file units are available 4 completely different sizes to match the frequent chain tooth profiles. Or, for about $27, you may get a equipment that comes with all of the spherical recordsdata, plus the flat file and gauges and guides. There are different corporations that make very comparable kits, and a few of them are good high quality instruments. I’ve been utilizing Oregon recordsdata for fairly some time and so they haven’t let me down, which is why I like to recommend them right here. 

As a aspect be aware, you don’t want the file information, however having one helps you get a extra constant angle and chew on every tooth. This makes the method quicker for most individuals.

Step 1: Discover the Right File Measurement for Your Chain 

In case you have the homeowners’ handbook to your noticed, the chain kind and file measurement wanted needs to be listed in there. Or, you probably have an aftermarket chain in your noticed, the package deal that the chain got here in can have the required file measurement listed on it as properly. However, what you probably have an outdated noticed and an outdated chain and also you don’t have these issues? Properly, if you happen to purchased the total equipment, you possibly can merely see which file most closely fits the tooth. 

Verify which one matches the curve within the chain that can contact the entire chopping floor of the tooth. If the file solely contacts one a part of the tooth, it’s too small, and if it’s solely touching the highest and backside with a niche within the center, it’s too giant. The file ought to match the curve completely and call all the curve. 

Clearly, it’s higher to simply have the proper data, however the guess-and-check technique will work if you happen to can’t discover the data on-line or in your handbook. 

Step 2: Connect the Information to Your File and Begin Sharpening

After getting discovered the proper file measurement, you possibly can slide the deal with on the file, and fasten the file information. The information has strains on it that you’ll line up parallel to the bar, which can assist hold you at a 30-degree angle. That’s the commonest angle for chopping the enamel. 

Recordsdata solely reduce in a single course, and so “sawing” forwards and backwards isn’t what you’ll wish to do right here. The recordsdata solely reduce when “pushing” them. The tip of the file is the place the chopping ought to begin, ending down nearer to the deal with. 

You’ll be able to file from both aspect of the tooth, however no matter you select, hold it the identical for all enamel, left and proper. So, you possibly can select to begin the tip of the file “inside” the chain and file outwards away from the tooth, or begin the tip on the “exterior” of the tooth and file inwards. Both manner, the file solely cuts as it’s pushed. You’ll be able to push with the deal with, and use your different hand out close to the tip to maintain the stroke flat and even. 

If the enamel are simply boring, and never closely broken, I often make three strokes on every tooth. I shortly examine to verify the entire curve is being sharpened from the highest of the tooth all the way down to the flat as the bottom of the aspect curve, and that the file is chopping the entire floor of the curve from the within to the skin. It’s best to be capable of really feel a slight burr on the highest and outdoors of the tooth. That permits you to know that you just apexed the entire chopping floor. I drag my finger alongside every tooth to really feel a burr, after which transfer to the following one. For broken enamel that hit a rock, you could must make further passes to take away the harm and lift a burr. 

I take advantage of a marker to paint the tooth I began on so I do know after I make it round the entire chain. You can too begin on the “break” within the chain, which is often marked by two chopping enamel in a row going through the identical manner, or a coloured hyperlink. Both manner works to maintain you oriented. 

After I’ve achieved all of the enamel going through a technique, I change to the enamel that face the alternative manner, and work my manner round once more. Keep in mind to modify arms with the file to maintain the chopping course the identical for left and proper enamel. Should you don’t wish to change arms, transfer your physique to the opposite aspect of the noticed, or flip the noticed round.   

Step 3: File the Depth Gauges

After getting sharpened all the cutters, the following step is to file down your depth gauges (or information hyperlinks). With the Oregon equipment, place the Depth Gauge Software over the chain, and align the slit over the depth gauge you wish to file. There might be somewhat little bit of the depth gauge sticking up with the chopping tooth. Watch out to not hit the cutter when submitting the information. Take your flat file and push it throughout the depth gauge till it’s flush with the depth gauge. It will often solely take a stroke or two. Some folks simply make one agency stroke on every depth gauge every time they sharpen. I’ve tried that, and it appeared to work. Should you don’t file your depth gauges, your cutter hyperlinks will shave off thinner and thinner chips each time you sharpen the chain, and finally, the chain gained’t reduce even when it’s razor sharp. The guides decide how deep a chew the chopping hyperlinks will take out of the wooden. Not taking down your depth gauges will end in slower and slower chopping.  

After you could have filed all enamel, and all of the guides, you’re achieved! It can solely take a couple of minutes when you get the grasp of it, and you’ll simply make up that point by ripping your noticed via logs prefer it’s a scorching knife via butter. You’ll be able to gasoline up, prime off your chain oil, and get to work.
