How To Measure A Chainsaw Bar

The Chainsaw is a saw that pierce or slices by harnessing her array of Teeth. These collections of Teeth are interwoven with a chain and a rotating guide bar. It is utilized in completing a plethora of tasks in firewood production, lumbering, resizing, and reshaping woods for industrial, domestic as well as commercial uses. 

If you are new to these things you may be wondering on how To Measure A Chainsaw Bar?

Believe me. It is easy & will take just 5 minutes to do when you learn the process.

A greater number of this tool are designed with bar and chain combination. These types of tools have wide applications during the milling processes of chainsaws and in aspects that are related with Arts.  

Some are also designed only for trimming of concrete while a wide collection of the tool has applications in trimming of ice. People who handle this tool are usually called Sawyers.

The size of bar takes an important role in cutting performance. If you want to use a chainsaw for small jobs, you should take chainsaw with 16-inch or smaller bar.

There are at least three types available

Laminated bar

It is the kind of bar that consist of a different lab to reduce the weight of the bar. 

Solid Bars

These kinds of bars are typically intended for professional use. They are designed with solid steel. They usually have a convertible nose since the cog at the bar no swears out faster than the bar. 

Safety Bars

These kinds of bars are stratified with a small cog at the nose. The essence of the small nose is to reduce the kickback effect. They are typically used on consumer source. 

How to measure A Chainsaw Bar: The 2-Step Guide

Now that you have an idea of what a chainsaw bar, it's time to move over to how to measure chainsaw bars. This piece of article will extensively teach you everything you need to know, to keep your chainsaw bar in a good condition ready to be deployed all the time.

The chainsaw bar is typically one of the most important part of a chainsaw. If you will ever have the need to replace your chainsaw chain, then it is very vital to know the measurement of the bar because if you ever err or misapprehend in your measurement, your chainsaw may become counterproductive. A chainsaw that is too long or too short for the bar will not work nor serve the purposes for which it was made.

The chainsaw bar length is determined step by step. Deciding chainsaw bar length is not always as complex as people like to label it. On the other hand, it is not as simple as placing your tape measure from one end of the bar to the other.

Talking about measuring a chainsaw bar length, it encompasses the entire cutting length, which includes the top and the bottom of the bar.

To decide or determine the length of a chainsaw bar, follow these simple and proven steps:

Step 1  

Since you are going to be handling the chain itself, some safety measures are very vital to take before beginning the measuring process. 

Step 2  

Go ahead and cut the dimensions, taking note of the ideal breadths and diameters. You can achieve this via the use of your measuring tape with less pressure from the Chain’s base. Take a look at the tool. Ensure that you quantify it accordingly, and then round up to the immediate or adjoining square and take cognizance of the number.

If you wish to discover full or complete bar length, you would have to remove the covering of the tool.  Harness the measuring tape to ascertain the complete dimension of the tool starting from one sharp edge to the next sharp edge.

The number you get from this measurement should be higher than the normal length for cutting as stated above.

With these simple guidelines, your chainsaw bar will be correctly measured.

Ideal length for cutting and the general Bar length

Sometimes, it might become very necessary for you to tinker the arrangements of your chainsaw. With this, you would have to change the change the chain and replace it with a new one; hence; apt knowledge of the chain dimensions become a cannot-do-without.

If you do not have this information accurately, then it might face massive hitches when trying to look for the user’s manual.

Interestingly, we might assume that the chain happens to pull out or lapse, taking the dimensions of he bar which is embedded with this idea would be your best shot at correcting the defects in the chain compartment.

You can measure the stretch or length of your chainsaw bar in two ways.

You either measure the cutting the length and the general dimension. These two basic measurement practices can sometimes be regarded as the real length or the true length. More so, there is a wide range of deviation among each of them.

The Length for cutting or the effective length

Many handymen and technical men believe that the use of tape in measurement is simple and straightforward.

Measuring Tape fits perfectly into this. It is the dimension or extent of the bar that protrudes from the covering. It is this area that actually handles the process of cutting and it is glaringly smaller in dimension than the total length of the Bar. There is ample need for you to ascertain he ideal length for cutting because it will assist you to choose the best size chain when buying.

The full Length of the Bar

Before setting out to purchase a chainsaw, or before choosing a chainsaw, you should have an in depth knowledge of the dimensions of the path of the Bar. Firstly, you should know he full length of the Bar, then the internal and external dimensions. This measurement should be very precise because it will assist you in choosing the most ideal chainsaw for every task.

The existing Bar is not baseless. Several measurements such as guage and pitch can be carried out on the old Bar. All measurements should be recorded in inches, and rounded-off to the nearest even number. While measuring with the Tape, always ensure that the measurement is started from the front lean and should end at any cutter that is close to the user.

All handymen should identify the importance of the bar length and buy them as required. With an old chain saw bar length, you can easily replace with new bar lengths when in need of replacements.

When to replace Chainsaw Bar

Giving the nature of the job a chainsaw does, ( like cutting wood and other materials ) the bar invariably wears and tears after a couple of first few uses. The challenge is usually knowing when to replace the chainsaw.

We have carefully outlined a few signs that will tell you when it's time to change your chainsaw bar.

If your chainsaw bar is curved, it is perhaps time to get a new one. To ascertain the straightness of the chainsaw bar, remove the bar and site down it like you would a firearm.

Twisted bars are a type of cracked bar. They are often straight on one side and not the same on the other. You will eventually notice a twist as you sight down the bar if there is one.

If the rails or the parts of the chainsaw bar that keeps the chains are damaged or cracked or squeezed, then it's time to purchase a new bar.  Trying to use the damaged rail will result into fruitless effort as it can cause dangerous situation while being used.

When making use of your chainsaw, make sure it's making straight cut. If you in any case notice that it is not making a straight cut, then you may need to inspect your bar for damage. A curved cutting is the typical sign of a damaged by.

From time to time, you should check if your bar or chain becomes dull or not. In case, it becomes dull, use a chainsaw file or sharpner to sharpen the bar or chain. There are many chainsaw sharpners that worth the money and can make sure chain, bar and chainsaw more long lasting.

As an owner or user of a chainsaw, you must know the three metrical units to match the accurate size of your chainsaw. The three metrics are given below.

Pitch, Gauge, and Number of links

How to measure pitch

The pitch is typically a description of how closely chains are linked to each other, although it does not always account for the number of the present links and total length of the chain.

The formula to measure the pitch is P= distance between any 3 rivers / two.

As entangled as it seems, most chainsaw display pitch measurement on the user manual.

Gauge Measurement

The gauge is known as the parts of chainsaw that fit into the source guide bar and at the bottom part. The gauge measures the thickness of the drive links. It comes in handy when it comes to matching the correct chain gauge; thereby making the chain fit into the guide bar perfectly. 

Number of Drive Links

If you do not know your drive links, it is best to count to get to the actual chainsaw hence the length measurement is decided by a combination of pitch and the number of drive links -- because generally, the number of links are not always displayed on the owner's manual so it requires you to count it manually. 

Chainsaws typically consist of several parts

Engine

Chainsaw engines are routinely a 2-stroke gasoline internal combustion engine or an electric motor driven by battery or electric power cord. The carburetor needs constant adjustment when operating in high or low altitude-- but electrically controlled carburetors make all adjustments automatically.

Drive mechanism

Typically, an eccentric clutch and cog, the divergent clutch expands with increasing speed when engaging a drum. on the drum is seated a fixed cork or an exchangeable one. The clutch does three major jobs, but most importantly it protects the operator in case a kickback occurs. If the chain break happens to stop, the drum and the clutch we released immediately.

Guide Bar

A stretched bar with a round end of wear defiant alloy steel typically 40- 90 cm in length

Oil holes

Oil holes are located at the end of chainsaw power head. The holes are meant to match with the outlet of the oil pump. Oil is pumped through the whole into the lower part of the gauge. 

Guide slot

This is where one or two bolts from the chainsaw run through. The clutch cover is placed on top of the bar and it becomes a form of security for the bolts.  The size of the chainsaw will always determine if one or two boats will be installed.

Wrapping Up

When you don't maintain or care for power tools in this manner, they become a waste in due course and cause you to lose money. As a result of this, it is advisable to ignore a power tool and you should not use it to work if you are not knowledgeable about its operations.

It’s quite imperative to take some safety measures like putting on a glove, eyes protection and high grade chaps of chainsaws while measuring a chainsaw bar so as to guarantee your protection from any harmful or accidental occurrence.

If you regularly make use of chainsaw in your place of work, then it becomes an advantage for you to know the steps to take in measuring the chainsaw Bar.

A major advantage is that the task is performed once and immediately you measure the dimensions and have derived the accurate measurements, you can then easily replace.

Cultivating the habit of adequately maintaining the Bar of your Chainsaw is very vital because it will increase the life of the chainsaw and curtail some unwarranted expenses. Have you ever thought of buying new parts to replace the old parts in your chainsaw?

This usually comes after taking your measurement and the full guide and procedure have been provided in details here. Greasing of the Bar of the chainsaw is vast and it requires the use of many chain oil for the various chainsaws. The oil is usually exhausted at a very fast rate because of the sawdust and divergence in compulsion.

Every Chainsaw with two strokes requires enough greasing and the engine can be well maintained by maintaining the ideal fuel-oil volume, usually between 2% and 5%. In electrical chainsaws, the Greasing is done throughout the lifetime of the engine.
