The clue is in the name! A chainsaw has two main parts: a saw blade built into a chain, wrapped around a long metal guide bar, and a small, one-cylinder gasoline engine. Chainsaw helmets with visors offer some protection; so too do chainsaw uniforms. Wayne’s Chainsaw Museum: A short video tour of Wayne Sutton’s chainsaw museum in the United States, will hundreds of saws dating from about the 1930s.
One of the earliest patents for an “Endless chain saw” comprising a chain of links carrying saw teeth was granted to Frederick L. Magaw of Flatlands, New York in 1883, apparently for the purpose of producing boards by stretching the chain between grooved drums. “Usually, each segment in a chain features small, sharp, cutting teeth. Each tooth takes the form of a folded tab of chromium-plated steel with a sharp angular or curved corner and two beveled cutting edges, one on the top plate and one on the side plate. Left-handed and right-handed teeth are alternated in the chain. Chains are made in varying pitch and gauge; the pitch of a chain is defined as half of the length spanned by any three consecutive rivets, while the gauge is the thickness of the drive link where it fits into the guide bar. The conventional”full complement” chain has one tooth for every two drive links. Lack of chain oil, or using an oil of incorrect viscosity, is a common source of damage to chainsaws, and tends to lead to rapid wear of the bar, or the chain seizing or coming off the bar.
There are deep grooves in the bar to keep the chain from flying off the bar and to keep the chain cutting straight. Gently file the materials of the bar, clutch drum, clutch shoes, sprocket, chain dogs, and teeth. Draw a chainsaw bar and chain as they are cutting a block.

How does a chainsaw chain work?
Saw chains operate by being propelled around a guide bar, removing material from the kerf by cutting chips from the side and bottom. In order to operate properly, the depth to which each tooth cuts must be limited to avoid it binding in the wood.
What makes a chainsaw cut?
One major reason a chainsaw curves to either the right or left during a cut is that it was unevenly sharpened. The unequal teeth of the chain cause it to take a different-sized bite into the wood. What is this? The uneven sharpness of the chain is mainly due to manual sharpening, especially with the use of a file.
What part of a chainsaw chain does the cutting?
The cutter is the part of the saw chain that does the cutting. The saw chain has left- and right-hand cutters so that the saw chain will cut evenly through the wood.
What is a chainsaw Raker?
Depth gauges, “riders,” or “rakers,” as they are sometimes called, control the amount of wood severed by a cutter tooth. During the life of a pro saw chain, they occasionally need maintenance for top cutting performance.
Why do chainsaws cut angles?
When you notice your chainsaw pulling to one side as you cut, or your chainsaw is cutting crooked, it’s likely there’s an issue with the chain, advises Madsen’s Shop and Supply. Check the size of the top plates, which sit on the longer sections of each tooth on the chain. These top plates should be the same size.
Why does my chainsaw jump when cutting?
Improper Chain Tension You can extend the life of your chain, bar and chain saw motor by maintaining the proper amount of tension on the chain. Too much slack in your chain can cause the saw blades to jump the bar. This is commonly referred to as throwing the chain.
What is a Dawg bolt?
noun (2) ” Definition of dogbolt (Entry 2 of 3) 1 : a long slim bolt for uniting two parts at right angles or for securing girders to a supporting post by being driven through one piece then bent and driven into the other. 2 : a bolt used to hold the work in machining.
What causes a chainsaw bar to bend?
A saw that has had one side of the chain nicked on a rock or dulled in the dirt will cut in a circle. A chain that has been sharpened differently on one side of the chain than the other will cut in a circle. A bent bar might cut crooked or straight, but, it will get hung up in the kerf.
What is chainsaw gauge?
Gauge. This is the thickness of the drive links (the tooth-like underside of the chain that fits in the guide bar). The chain gauge is measured in inches and will usually be in the manual or on the chainsaw itself.
What does the gullet do on a chainsaw chain?
The gullet forms the space between the actual tooth and the raker. The depth gauge, or raker, is what prevents the chisel edge of the tooth from biting in too much into the wood. The difference in height between the raker and top plate determines the depth that the tooth cuts with each pass around the bar.
What are the chain called on a chainsaw?
Cutter teeth are one of the types of links on your chainsaw. The cutter teeth come in two parts; right-hand and left-hand cutters. These teeth are the meat and bones of your chain. They are the cut force of the blade itself and chip away at the wood you are using your chainsaw on.
Can a lion climb a tree?
Lions are believed to climb trees as a behavioral adaptation to protecting themselves from the constant irritation of insect bites while lazing on the ground under trees. Some animal behaviorists claim that these lions have perfected the art of climbing trees as a way of escaping the sweltering heat on ground level.
How do you carry a chainsaw chain on a saddle?
The chainsaw stays securely on the saddle and can still be accessed quickly. To counterbalance the weight of the saw it is a good idea to also carry a Rifle Scabbard or saddle bag attached on the left side of the saddle. A plastic chain guard is riveted inside the bar piece to protect the lather from the chain.
