First Chipper Chain!

Did you know a larva revolutionized the chainsaw chain?

In 1946, Logger/inventor Joseph Cox observed the Timber beetle C-shaped jaws as it was chewing in a tree stump. And he went home and in his basement he invented the first Chipper Chain. It was produced and sold in November 1947. It is still widely used today. It’s the biggest influences in the history of timber cutting.

Many chainsaw users are familiar with the Timber beetle larvae. Especially chainsaw carvers, when the larvae bore out of their carving.  Researchers from the University of Missouri and Texas A&M identified 3 ways of getting rid of the larvae. Insecticides (such as Tim-Bor and Bora-Care), Heat (larvae must be exposed to 120 degrees or more for at least 2 hours or more.), Cold (zero degrees for two weeks or more.)

A little fact on Chipper Cutter Chains

Why is it so hard to find chipper chains these days?

 The answer is they are being replaced with the chisel type chains. Or more accurately the Semi-Chisel chains. The chipper chains are being faced out because they are to slow for the job they are being used for. Joseph Cox invented them in 1947. The “C” shape of the timber beetle larvae inspired the design. Sounds weird but its true. Joseph Cox was one of the founding fathers of the Company Oregon. Oregon still offers one chipper chain, the 11BC chain. It’s used for larger forestry equipment.

We will be coming out with a video on the different types of cutter chains like:

- Chipper

- Semi-Chisel

- Chisel

- Chamfer Chisel

- Micro Chisel

In the video we will be going in depth of each one and what is best for you needs. So stay tuned to our YouTube Channel. The link below will send you directly to our channel.

Low-Profile Chains and Standard Chains

While looking for a 3/8" chain with a .050-inch gauge, one might ask what is the difference between a 3/8" low profile chain and a standard 3/8" chain.

Today I will try and help you understand that difference.

Low Profile Chains were developed in the early to mid 1970s and later incorporated the standard low kickback safety standards required by ANSI.

There are 2 pitches for the low profile chains 1/4" and 3/8".

The low Profile chain is lighter in weight and size requiring less power to operate and is design was for both electric and gas powered chainsaws with engine sizes up to 42cc.

A standard chain is designed for chainsaws with engine sizes 50cc and up.

The primary difference between a low profile and standard 3/8" pitch, .050" Gauge can be found in the cutter height and the height of the drive link.

If you are uncertain as to whether your chain is a low profile or not you can print out the chain reference PDF located in our how to section.

Make sure you printer option is set to actual size when printing.

Match your chain to the chain on the chain reference chart.  Chains with the red colored numbers are low profile. Chains with the white numbers are standard.

The next question one may ask is can a low-profile chain fit on a chainsaw bar designed for a standard chain. Providing the pitch and gauge is the same the technical answer is yes. However we do not recommend this as the gap between the chain and the bar will require more oil demand and increase debris build up.

A standard chain will not fit on a chainsaw bar designed for a low profile chain.

Random Facts!

Here are a few facts about chainsaws.

U.S. Consumer Product Safety Commission shows that reported chainsaw injuries were:

• 30,928 in 2010
• 30,212 in 2011

Interestingly enough most of the head injuries were due to falling trees and branches and not by the chainsaw.

If you or someone know is part of this statistic please check out our safety equipment section.

A Redneck and a Chainsaw

A redneck walks into a hardware store and asks for a chain saw that
will cut 6 trees in one hour. The salesman recommends the top of the
line model. The redneck is suitably impressed, and buys it.

The next day he brings it back and says, "This chain saw is defective.
It would only cut down 1 tree and it took all damn day!"

The salesman takes the chain saw, starts it up to see what's wrong, and
the puzzled redneck says, "Heck, what's that noise?"

How to determine chain length

Most people ask how do I determine the length of my chain? The length of your chainsaw isn't determined in inches or centimeters but rather by drive link count. Simply put, chain Length equals drive link count.

Most dealers of chainsaws will ask you what your drive link count is. They simply want to know how many drive links there are. Which determines the length of your chain. This is very important for replacing your chain. If the chain you are replacing does not match the one you are replacing it with it can cause serious injury to you and your chainsaw.

If you will mark the place were you have begun counting your drive links this will better help you avoid counting a drive link more than once. You can mark the chain with chain with chalk or whiteout. You will need to count each drive link.

You can also check out our video on chain length for more information.

What is Pitch?

Knowing the pitch of your chainsaw is very important. You will need to know it when replacing your chainsaws bar or your chain.

Pitch is the distance between any three consecutive rivets divided by two. Most cutting elements on your chainsaw are Pitch related. The most common way for you define the pitch of your chainsaw is the information stamped on the bar itself, which we will help you define in another video.

             

                  Most Common Pitch Sizes:

• 3/8" Low Profile
• 3/8 Full Profile
• .325"
• .404"
