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.
In learning how steel chainsaw guide bars are made, we started with the 3-part guide bar process. The last step with how steel chain saw guide bars are made has to do with painting the chain saw guide bar. Seeing how steel chain saw guide bars are made revealed a largely automated process that leaves little room for error.
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.
Whether these saws were used for working on wood is not known. Up until the 16th Century there is no proof, that hand saws were used in forestry work. To some extent the saw was unknown and in certain places the felling of trees using a saw was forbidden.
how is a chainsaw built Related Question:
What metal are chainsaw chains made of?

What does full chisel mean on a chainsaw chain?
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.
Is a chainsaw bar high carbon steel?
The steel in most chainsaw bars is high-quality steel that will keep an edge well, but has enough flex to bend under stress rather than break or crack. The metal is generally corrosion resistant, and many bars are a stainless-steel alloy.
Are chainsaw chains hardened?
chainsaw chain is not made out of air hardening steel.
Can a chainsaw cut metal?

What is the most aggressive chainsaw chain?
404 chains are the most aggressive. The 3/8 is a more flexible size with adequate strength, low weight and substantial cutting speed. It can also can handle the power of a 50-100cc chainsaw engine.
What is a chainsaw tooth?
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. Cutter teeth come in different types too, which are called cutting tooth profiles.
What does a clutch do on a chainsaw?
The clutch allows the engine to turn freely at low rpm [rpm=revolutions (turns) per minute] without moving the chain. They are separate. Unlike a four wheeler or truck, the chainsaw operator doesn’t have to engage the clutch or put the chainsaw in gear.

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.
Does a woman’s pelvis break during childbirth?
The left and right bones of your pelvic girdle are joined at the front by a narrow section of cartilage and ligament. This is called the pubic symphysis, or symphysis pubis. As the pelvic bones loosen during pregnancy, the pubic symphysis can temporarily separate. This is not a dangerous condition.

Currently the procedure is rarely performed in developed countries, but is still performed in “rural areas and resource-poor settings of developing countries” where caesarean sections are not available, or where obstetricians may not be available to deliver subsequent pregnancies.
Can a chainsaw cut through bone?
