The original chainsaw looked more like a modern-day kitchen knife than what we would call a chainsaw nowadays. In the 1780s, in a bid to make the removal of the pelvic bone easier and less time-consuming two doctors named John Aitken and James Jeffray invented the chainsaw. In 1883, a patent for a chainsaw for cutting boards was passed and then subsequently more and more chainsaws developed.
The original chainsaw was invented and used by two Scottish doctors in the 1780s. Interestingly, it’s also the first Stihl chainsaw because the first wood chainsaw was invented by Andreas Stihl – the founder of the Stihl chainsaw company. Stihl also claims to have invented the first chainsaw for use by one person in 1950 – check out all the Stihl chainsaw years made for more info.
Now people are obsessing over the origins of the chainsaw, after TikTok user hellomynamesjon shared a video saying it was first invented to help with childbirth, which sounds more than a little terrifying. Yes, the first chainsaw really was invented to be used in childbirth – though thankfully it was a far cry from the electric-powered monsters people cut down trees with today. Modern chainsaws come in many sizes, from small electric saws intended for home and garden use, to large “Lumberjack” saws.
The modern-day chainsaws we’re used to seeing are mainly utilised for tree cutting. Shockingly, the chainsaw was originally invented to assist in childbirth – yes, you read that correctly. The doctors’ chainsaw was used during symphysiotomies.
why does a chainsaw work Related Question:
How does a chainsaw work?
Most simply put, a chainsaw works by spinning a chain of saw blades, also called “teeth”, around a guide bar quickly to cut through wood in a fast, smooth motion. Sizes of blades/teeth and guide bars can vary greatly between chainsaws.
What causes a chainsaw not to run?
The chainsaw’s engine is flooded with fuel. A fuel issue is one of the most common reasons why a chainsaw won’t start. If the operator has repeatedly been trying to start the chainsaw through the recoil starter system, they may have accidentally flooded the engine with fuel.
How did chainsaws help deliver babies?
Two doctors invented the chainsaw in 1780 to make the removal of pelvic bone easier and less time-consuming during childbirth. It was powered by a hand crank and looked like a modern-day kitchen knife with little teeth on a chain that wound in an oval.
Can you cut wet wood with a chainsaw?
Can you cut wet wood with a chainsaw? Yes, you can cut the wet wood with a chainsaw. Besides, there is a misconception that wet wood can impact the chainsaw bar and chain. But actually, the damp wood will not dull the chainsaw any faster than using it on other types of wood.
How do you start a stubborn chainsaw?
Try to start the chainsaw after priming the carburetor. 5. Activate the choke by moving the lever to the full choke position and pull the starter rope 3 or 4 times to start the engine. If that doesn’t work, move the choke lever to half choke and pull the starter rope, 6 times maximum, to start the engine.
Why does my Stihl chainsaw dies when I give it gas?
An engine stalls when it’s getting too much or not enough fuel from the carburetor. Stihl chainsaw carburetors usually have three adjustment screws: one each for idle, low speed and high speed. If the saw stalls while it’s idling, adjusting the idle screw, which usually is marked LA, should help.
When did they stop using chainsaws in childbirth?
In light of this success, the chainsaw was eventually mechanized in the later 19th century to increase its ease of use by OB/GYNs on expectant mothers. However, shortly after this, the chainsaw was superseded by the Gigli twisted wire saw, which was most commonly used to cut bone.
Where do they cut for episiotomy?
An episiotomy is a cut (incision) through the area between your vaginal opening and your anus. This area is called the perineum. This procedure is done to make your vaginal opening larger for childbirth.
How often should you flip the bar on a chainsaw?
Some professional loggers would advocate that you should flip your chainsaw bar at the end of every use, particularly when you are cleaning up. Others suggest a more relaxed approach advising that you flip the chainsaw bar only when you are changing your chainsaw blade.
Why does my chainsaw bar smoke?
This most commonly is a result of a dull chain and exerting to much pressure on the bar and chain trying to make the chain saw cut. This could also be either a lack of bar and chain oil ( tank empty, restricted oiler hole ) or an inferior type of oil that is being slung off the chain and not lubricating.
How often should you change your chainsaw chain?
The chain sprocket must be replaced if the depth of the wear marks reaches about 0.5mm, i.e. the wear limit. A seriously worn chain sprocket can cause the chainsaw chain and guide bar to wear at an increased rate, as well as reducing cutting performance too, so it’s important to keep an eye on.
Why does my chainsaw dies when I give it throttle?
If the filter becomes clogged, not enough fuel will reach the engine for it to run properly. Because your chainsaw will idle, but dies when it is revved up to full power, it means that the filter is only partially clogged; it will allow enough fuel to the engine to run on idle, but not enough to sustain full throttle.
Should you let a chainsaw warm up?
The gas engine in a gas chainsaw should warm up, but due to the engine’s small size, this will happen quickly. Normally the engine will run for a short time after startup before you really start using it, giving the oil enough time to warm up and lubricate all engine parts.
Why does my chainsaw only runs on choke?
When your chainsaw only runs if the choke is on the problem, in most cases, is a result of fuel supply problems or a faulty carburetor. To fix the problem you should check and clean the fuel system and carburator.
What’s the best angle to sharpen a chainsaw chain?
Always file at right angles to the guide rail. The right sharpening angle depends on the saw chain and the wood that you want to cut. The sharpening angle will generally be between 25° and 35° – the harder the wood, the greater the angle.
