Measuring a chainsaw bar accurately is essential for selecting the correct replacement bar or chain. An incorrectly sized bar can damage the chainsaw or be unsafe to operate.
To measure a chainsaw bar, follow these steps:
- Locate the bar’s length stamp. This is usually a series of numbers stamped into the side of the bar, near the base.
- Read the length stamp. The length stamp will indicate the length of the bar in inches. For example, a bar with a length stamp of “18” is 18 inches long.
- Measure the bar from the tip to the base. This will give you the overall length of the bar, including the nose and tail.
When choosing a replacement bar, it is important to select a bar that is the same length as the original bar. A bar that is too short will not be able to cut effectively, and a bar that is too long will be difficult to control.
1. Length
The length of the bar is the most important measurement to consider when choosing a chainsaw bar because it determines the cutting capacity of the chainsaw. A longer bar will allow the chainsaw to cut through thicker pieces of wood, while a shorter bar will be more maneuverable in tight spaces.
When measuring the length of a chainsaw bar, it is important to measure from the tip of the nose to the base of the tail. The length stamp on the side of the bar will typically indicate the length of the bar in inches. For example, a bar with a length stamp of “18” is 18 inches long.
It is important to note that the length of the bar is not the same as the length of the chain. The chain must be long enough to wrap around the bar and engage with the sprocket, but it should not be too long, as this can lead to premature wear and tear on the chain.
2. Width
The width of the chainsaw bar is important because it determines the size of the chain that can be used. Chainsaw chains come in a variety of widths, and it is important to use a chain that is the correct width for the bar. Using a chain that is too narrow or too wide can damage the bar and the chain.
- Chain Width: The width of the chain is determined by the number of drive links it has. Drive links are the links that engage with the sprocket on the chainsaw. The most common chain widths are .325″, .375″, and .404″.
- Bar Width: The width of the bar is measured from the inside of one groove to the inside of the other groove. The most common bar widths are 1.3mm, 1.5mm, and 1.6mm.
- Matching Chain and Bar Width: It is important to match the width of the chain to the width of the bar. Using a chain that is too narrow or too wide can cause the chain to derail or skip off the bar.
When measuring the width of a chainsaw bar, it is important to measure the distance between the inside of the two grooves. The width of the bar will typically be stamped on the side of the bar.
3. Gauge
The gauge of a chainsaw bar is an important factor to consider when choosing a replacement bar. The gauge is measured in millimeters, and it refers to the thickness of the metal used to make the bar. A thicker gauge bar will be more durable, but it will also be heavier. A thinner gauge bar will be lighter, but it will not be as durable.
- Durability: A thicker gauge bar will be more durable than a thinner gauge bar. This is because the thicker metal is less likely to bend or break. A thicker gauge bar is also less likely to wear out over time.
- Weight: A thicker gauge bar will be heavier than a thinner gauge bar. This is because the thicker metal weighs more. A heavier bar can be more difficult to handle, especially when working for long periods of time.
- Price: Thicker gauge bars are typically more expensive than thinner gauge bars. This is because the thicker metal is more expensive to produce.
When choosing a chainsaw bar, it is important to consider the trade-offs between durability, weight, and price. If you need a bar that is durable and can withstand heavy use, then a thicker gauge bar is a good choice. If you need a bar that is lightweight and easy to handle, then a thinner gauge bar is a good choice. If you are on a budget, then a thinner gauge bar is also a good choice.
4. Nose
The shape of the chainsaw bar’s nose is an important factor to consider when choosing a chainsaw. The nose of the bar is what actually cuts through the wood, so its shape will affect the chainsaw’s cutting performance.
- Cutting Speed: The shape of the nose can affect the cutting speed of the chainsaw. A nose with a sharp point will cut faster than a nose with a dull point.
- Cutting Efficiency: The shape of the nose can also affect the cutting efficiency of the chainsaw. A nose with a sharp point will cut more efficiently than a nose with a dull point. This is because a sharp point will create less friction with the wood.
- Control: The shape of the nose can also affect the control of the chainsaw. A nose with a sharp point will give the operator more control over the chainsaw, making it easier to make precise cuts.
When choosing a chainsaw, it is important to consider the shape of the bar’s nose. The shape of the nose will affect the cutting performance of the chainsaw, so it is important to choose a nose that is suited to the type of cutting you will be doing.
5. Tail
The tail of the chainsaw bar is an important part of the chainsaw. It is what attaches the bar to the chainsaw, and it must be the correct size and shape to fit properly. If the tail is too small, it will not be able to properly support the bar, and the bar may come loose or break. If the tail is too large, it will not fit properly into the chainsaw, and the chainsaw may not be able to function properly.
When measuring a chainsaw bar, it is important to measure the tail as well. The tail should be measured from the end of the bar to the center of the mounting hole. The measurement should be accurate to the nearest millimeter.
Once you have measured the tail, you can use this measurement to find a replacement bar that will fit your chainsaw properly. It is important to note that not all chainsaw bars are the same, so it is important to find a bar that is specifically designed for your model of chainsaw.
By following these steps, you can ensure that you have the correct size and shape chainsaw bar for your chainsaw. This will help to keep your chainsaw running properly and safely.
FAQs about How to Measure a Chainsaw Bar
Measuring a chainsaw bar correctly is essential for selecting the correct replacement bar or chain. Here are some frequently asked questions and answers about how to measure a chainsaw bar:
Question 1: What is the most important measurement to consider when measuring a chainsaw bar?
Answer: The length of the bar is the most important measurement to consider. The length of the bar determines the cutting capacity of the chainsaw.
Question 2: How do I measure the length of a chainsaw bar?
Answer: To measure the length of a chainsaw bar, measure from the tip of the nose to the base of the tail. The length stamp on the side of the bar will typically indicate the length of the bar in inches.
