Chainsaws help millions of people to cut woods. You will love the feeling of using a chainsaw to cut precisely through the wood. The precision depends on the sharpness of the chainsaw teeth. It can be a challenge to cut precisely if the chainsaw is not sharp enough. It is frustrating when you are working with a chainsaw and suddenly see that it is blunt to the point where it is useless.
Cutting dirty logs or cutting near the ground can make the chainsaw blunt. It is especially frustrating if one side of the teeth gets dull only. When this happens, it causes the chain to deflect sideways rather than following a precise curve. This may cause the bar to get blocked in the kerf.
What you need to do is to make the chainsaw sharpened enough to work back on. One way to sharpen is through using a grinder. Grinders can sharpen fast putting you back to work in no time. Sharpening with a grinder can be done at the needed angle, which can be tough otherwise.
Preparation before the grinding
Before starting to grind the chainsaw, preparation is necessary. Get a pair of gloves to cover your hand. It is also advisable to get a pair of goggles to cover your eyes. Another preparation is to make sure the specifications are clear. This means that you should make a check on the blade specifications before commencing the sharpening. Information about the gauge and the pitch should be clear to you. The specifications are usually available in the user’s manual that came with the box that the blade was in. Nowadays, the internet can help you get the specifications if you lost the manual.
Get a chainsaw grinder
Get online or at a local hardware store and you can buy a chainsaw sharpener grinder. The best advice is to buy an angle chainsaw grinder, especially if you are at home because it can be handheld. The one fitted on the table is good if you are looking for stability while also ensuring less risk of an accident.
Look for a safe place
The next step is to look for a safe place, especially away from children. It is best to be safe than sorry. Holding the chainsaw safely is also very important, given the fact that the disc is very sharp. The disc can become blunt after use over time, but you can sharpen it by putting the disc against the stone and running the chainsaw.
Sharpen your chainsaw
The next step is to sharpen the chainsaw. Place the chainsaw on a table at a height that is comfortable for you to work. Then get a good grip on the grinder and find out the chains which are attached to it. Make sure you take off the chain from the saw and place it on the rail in the grinder. The rail will have to be rotated to ensure that both sides of the chain are grinded. However, you must make sure that the height reaches the right places.
Start the Grinder
Start the grinder now that we have reached the point to get the sharpening done. It is best to start slowly and increase the pace with control. The spikes are on the alternating direction and so either you can work on every other spike or rotate the chain and work on each spike. The way you want to work depends on your comfort. Some like to get each spike done together while others prefer to work on one side throughout the chain first.
After a while, you will get the chainsaw ready and sharp, thanks to the grinder and your effort. Be careful not to hurt your fingers in getting the sharpening done.
Chainsaw sharpening tricks
One of the tricks to sharpen a chainsaw is to apply the file that is of the right size. When the right size file is applied, the chain can be sharpened quite fast. The 80/20 rule can be achieved which means that when the file is 80 percent inside the cutter and the remaining 20 percent is above, then a sharp, crescent-shaped hook can be attained. On the other hand, the small-sized file can prohibit the sharpening of the cutter while the large file can remove the hook.
Lowering the depth gauge
Rakers or depth gauge control the depth of the cutter teeth, and so the depth gauge should be lowered. Smaller chips may be seen if the depth gauge is not filed properly.
Brace the chainsaw
One of the sharpening technique is to brace the chainsaw by placing the bar on a bench vice. The pressure applied should be even as well as consistent. A stump vice can be used when sharpening with a field.
The backward motion of filing
Filing from the inside of the tooth to the outside is another way to ensure that the sharpening is done properly. If the file is applied from the exterior to the interior part, there are chances it would wear out the file. The strokes can also be more consistent when the filing is done from the inside towards the exterior of the tooth.
Chainsaw sharpening angles
There are different types of chains, and hence the sharpening angles also vary. Crosscut chains usually have a sharpening angle of 30 degrees. This can be achieved through a file and witness marks can help in matching the file angle. However, this may not be possible with all chains because many chains do not have a witness mark. Typically, the angles are marked on the jigs so that the filing angle can be accurately placed.
In conclusion, we have come to understand that a sharp chainsaw can give you a precise cut on woods. Making a chainsaw sharp is a need that can be accomplished. One way to sharpen a chainsaw is by using a file to hand sharpening method. The other method is applying a grinder. Here we discuss how you can sharpen the chainsaw with a grinder.
