Most homeowners will need to replace their roof at some point. How do you know when it’s time for a new roof? You should be inspecting it periodically to keep on top of repairs and be well aware of when you need to replace it. This is especially important if you live in a region with harsh or extreme weather, as that can cause damage to shingles or cause water buildup and leaking.
The circular saw was invented by French immigrant Edmond Michel in 1924. While living in New Orleans in the early 20s, Michel had observed a group of farmers painstakingly hacking away at sugar cane with large machetes. Michel began to experiment by mechanizing the machete. In 1923, Michel created a motorized machete with a 6-inch saw blade mounted on a carved wood frame and equipped with a motor from a malt mixer, creating the first electric handsaw.

When purchasing a circular saw, consider the two types: worm drive and sidewinder. Depending on the application, you’ll prefer one over the other. Geography certainly plays a role in popularity of either saw. The worm drive is most popular in the west and Midwest, while the sidewinder is more popular in the east. However, in either region, it’s not uncommon to own both.
The body of the worm drive circular saw is narrower than the sidewinder. It’s heavier and has a thicker, sturdier shoe. The motor of the worm drive is built toward the rear of the tool and the power is transferred to the blade by a pair of gears situated at a 90-degree angle of each other. The gear setup reduces the speed of the blade to about 4500 RPM. However this increases its torque. Because the motor is positioned in the rear, you have a much longer saw. The length of the saw comes in handy when cutting wider stacks of lumber. The blade on the worm drive is on the left part of the tool, so most of the motor weight is on the right. This makes it easier to follow a cut line. The shape of the worm drive also makes plunge cutting easier. One downside of a worm drive saw is that because there are additional gears, you will need to maintain the oil levels.
The sidewinder saw has a motor in line with the spinning blade. This brings the speed of the blade around 6000 RPM. The motor position allows for a lightweight, compact saw. The lighter weight makes the sidewinder ideal for overhead projects. Another benefit of having the blade on the right is the weight of the motor rests on the solid part of the board, rather than the cutoff. A downside is that it’s difficult for the carpenter to see the cutline while cutting. Three benefits of owning a sidewinder are that you have the option of going cordless, they are less expensive and they don’t require oil.

Brushless motors have been around for many years. Only recently have they entered the power tool market. Tool companies are starting to use these motors to make their drills and impacts more efficient by pairing this motor with computer chips and lithium-ion batteries.
These components work together in three ways:
The computer chips control the motor, so it only works as hard as it needs to.
Without using brushes, the motor saves battery life, as brushes may cause unnecessary friction.
The battery powers the computer chips, so they all work together to make a more efficient tool.
Companies say these types of drills last longer because they run cooler and more conservatively. Soon, companies will be releasing power tools with this same technology in more than just drills. There’s no telling where this technology could take us. Check out toolbarn.com to see all of our brushless selections.
