To find the called length of your chainsaw bar, measure it from its front tip all the way back to the cutter closest to the body of the saw. Round this measurement up to the nearest even number in inches. For example, a bar that measures 18 3/4″ will actually have a called length of 20″.
How is chain size measured?
Measuring the size of a chain requires a simple tool such as a set of calipers. Pitch is measured by finding the distance from the center of one pin to the center of the next pin in line.
How do I know what size chain is on my Stihl chainsaw?
If you are replacing a Stihl® chain, you can look at the numbers on the side of the chain to determine pitch, gauge, and other characteristics of the chain. Example: Your chain has the number 33RM2 stamped in the side of it. The last three numbers (or letters) denote characteristics of the chain.
How do I measure my anchor chain?
Determining how long your anchor rode should be is as simple as multiplying the deepest water you expect to anchor in by 8. As for rope size, the rule of thumb is 1/8″ of rope diameter for every 9′ of boat length. So if you expect to anchor your 26′ boat in 30′ of water, you need 240′ of 3/8″ nylon rope.

72 = 3/8 pitch .050 gauge or 1.3mm. 73 = 3/8 pitch .058 gauge or 1.5mm.
How do you measure a tow chain?
To measure the chain size, if you have just the sprocket, use calipers to measure between the teeth. Measure from center to center of where the chain roller would set between the teeth that will give you the pitch. Once you know the pitch you can determine what chain size you would need.
What is the difference between Stihl green and yellow chain?
Others will chime, looks like green is homeowner (and dirty condition) safety chain. That stays sharper longer in dirty conditions. The yellow looks like full chisel, cuts faster but dulls quicker.
How do you pick a sprocket size?
Determine the number of teeth of the small sprocket. The number of teeth for the large sprocket is determined by multiplying the number of teeth for the small sprocket by the speed ratio. More than 15 teeth on the small sprocket is recommended. The number of teeth on the large sprocket should be less than 120.
How do I know what kind of sprocket I have?
Number of sprocket teeth or sprocket diameter. . . The easiest way to determine the number of teeth is simply to count them. Sometimes, however, the teeth are totally worn away. In this event, the caliper diameter may assist in identifying the sprocket.

What is the length of anchor chain?
When a medium sized ship anchors about 5 shackles are paid out. Assuming that the ship has anchored at slack water, there may be only 2 shackles forming the catenary. A shackle is a unit of length and equal to 15 fathoms or 90 feet and is the standard length of a chain .
How do you size a mooring?
Mooring Pendant Length should be about 2 1/2 times the boat’s freeboard. Diameter should be as large as is practical—but it must be able to fit through bow chocks and around a bow cleat. Effective chafe protection is recommended for the point where the pendant passes through a chock.
How big is an anchor chain?
The chain portion of these rodes is typically six to 30 feet long. For boats up to about 30 feet, a general rule of thumb is a boat length of chain.
What’s the difference between 404 and 3/8 chain?
Secondly, the numbers 3/8″ and . 404″ refer to the pitch (distance) between the drive links – these are the bits on the chain that stick down and engage with the drive sprocket on the saw, and the sprocket on the roller-nose end of the bar.
What chainsaw chain cuts the fastest?
A full chisel chain is a chain with square cornered teeth, and they’re known for being the fastest cutting blade shape available. A full chisel chain also has a higher number of teeth than other chain options(full chisel is also known as a standard chisel chain).
What do Stihl chain numbers mean?
The Stihl company stamps its chains with a number, called a Marketing Number, that will help you identify the size of the chain. A 1 equals a 0.043-inch gauge, 3 equals a 0.050-inch gauge, 5 corresponds to a 0.058-inch gauge, 6 means the chain has a 0.063-inch gauge.
What chainsaw chains do professional loggers use?
Full-chisel teeth chains are usually used by professionals on large saws. Semi-chisel teeth are rounded, so the risk of kickback is less, and they stay sharper longer. Semi-chisel teeth cut slower but are a better choice in dirty wood than full chisel.
What does full chisel chainsaw chain mean?
A full chisel chain is designed for the fast cutting action. In comparison to the semi-chisel chain, this chain has square-cornered teeth which makes it more aggressive when cutting.
What’s the difference between full chisel and semi-chisel chains?
The sharp corner of the full chisel cutters split wood fibers easily and provides the fastest, most efficient cutting in clean softwood. The corner of the cutters on a semi-chisel saw chain are slightly rounded.
What tooth sprocket should I use?
So, the bottom line is, what are you trying to achieve? For more bottom end and faster acceleration, use a small countershaft/front sprocket or large rear sprocket. For every 1 tooth that you change on the front sprocket is like changing 3 to 4 teeth on the rear (and that’s true for higher gearing ratios, too).
Is a bigger or smaller sprocket better?
Substituting a larger front or smaller rear sprocket lowers the ratio (sometimes called “taller” gearing), resulting in more speed for a given engine rpm. Likewise, a smaller front or larger rear sprocket gives less speed for a given rpm (“shorter” gearing).
What should be the minimum number of teeth on sprocket?
Ideally sprockets should have a minimum of 19 teeth.
How do you measure a chainsaw chain?
Measure the distance from the tip of the chainsaw bar to the point where the bar first emerges from the saw’s casing. A tape measure will provide that information. Round the measurement up to the nearest even number if the figure was uneven or fractional. The resulting number is the bar measurement.
How do I know what size my chainsaw chain is?
Simply put, the type of chainsaw file you need directly corresponds with the size of your chain pitch. The larger the pitch will mean the higher the cutting teeth will be. The higher the teeth will therefore mean the larger the file will need to be.
What size file do you use on a 3/8 chainsaw chain?
Yes the 7/32″ file is a perfect size for sharpening standard 3/8″ pitch chain (not 3/8″LP low profile).
What size tree can a 14 inch chainsaw cut?
Cutting down medium size trees with a trunk of about 14″ to 16” will require a larger chainsaw of about 16″ to 18” to fell the tree in one easy pass.
Are all chainsaw depth gauges the same?
A: When depth gauges are uneven, each cutter tooth on the chain takes a different sized bite. This causes the chain to cut rough and vibrate. If the depth gauges are higher on one side than the other, this causes the chain to cut crooked. The cut will pull in the direction of the side that has the lower depth gauges.
What size chain do I need?
After a measurement is obtained, its a good idea to opt for a necklace size that is at least the second size up from your neck size. For example, if you have an 18 inch neck, you should probably choose a chain length of 20 inches or more. An 18 inch chain would feel too tight.
What size is number 2 chain?

Can I put a 20 inch bar on a 18 inch chainsaw?
A chain saw engine turns a sprocket. Changing the bar and chain on your 18-inch chain saw to a 20-inch size will enable easier cutting of larger trees and branches. Larger chain saws cut through thicker trees and limbs. Put work gloves on to protect your hands and fingers.
Does gauge matter on chainsaw chain?
The gauge measurement of a saw chain tells a pro user about the strength of a chain’s drive links. Thicker drive links are usually stronger, but they are heavier. Weight affects performance, and to maximize cutting speed, weight should be kept to a minimum.

To measure, wrap a soft tape measure around your neck, keeping the tape measure parallel to the floor as you measure. Then, add 2 to 4 inches (5 to 10 cm) to your neck measurement to calculate your minimum recommended chain length.
How often should you sharpen chainsaw blade?
A chainsaw may only need to be sharpened once a year if it is rarely used, but a tool that is frequently used will need to be sharpened regularly to ensure that the blade doesn’t get too dull. On average, a chainsaw blade will retain its sharpness for about 3 hours of actively cutting through wood.
What is a 3/8 pitch chain?
If you decide to measure the pitch yourself, just remember to measure between the middle points of 3 rivets on the chain, and then divide the number by 2. So, for a 3/8″ pitch chain, the measurement between three links would be 3/4″ (. 75″), which is 3/8″ (. 375″) when divided by 2.
