Summary:
The video is about table saw safety and how to use a table saw safely.
In the beginning of the video, the host mentions that there are over 60,000 table saw injuries per year in the U.S., and three thousand of those result in amputations. He emphasizes that safe table saw use is important.
The host then goes over two common causes of table saw injuries: kickback and grabbing an off-cut workpiece before the blade stops spinning. He explains what kickback is and how to prevent it using a riving knife or a splitter. He also says that it is important to never grab an off-cut workpiece before the blade stops spinning, and that you should always use a push stick or push block to push the workpiece through the cut.
Next, the host talks about some general setup principles that apply to everyone no matter what kind of saw you own. These principles include making sure the fence is parallel to the miter slots, keeping the bed of the saw waxed, and wearing hearing and eye protection.
The host then talks about how to select a blade. He says that the blade that comes with a new table saw is usually junk, and that you should buy a new one. He also says that it is important to use the right blade for the job. For example, you should use a rip blade for ripping cuts and a crosscut blade for crosscut cuts.
The host then goes over how to make rip cuts and crosscuts. He explains how to position your body and how to use a push block or push stick. He also mentions that you should never use the fence and the miter gauge at the same time, as this can cause kickback.
Finally, the host talks about table saw safety devices, such as blade guards, featherboards, and SawStop. He says that blade guards can help to prevent kickback, but that they are not foolproof. He also says that featherboards can help to keep the workpiece stable and prevent kickback, but that they are not a substitute for safe practices. SawStop is a saw that has a safety feature that can stop the blade if it comes into contact with skin. The host says that SawStop is a great safety device, but that it is not required for safe table saw use.
Overall, the video is a great resource for anyone who wants to learn how to use a table saw safely. The host covers a lot of important information in a clear and concise way.
