In this episode:

In Tool Lab, Nathan Gilbert talks all about saw blades. Having the right blade can significantly impact the table saw’s performance, quality of the cut, and safety. He explains that the stock blades on a table saw are for general use and not the best quality. Table saw blades come in three categories: ripping, cross-cutting, and combination. Nathan then goes into the blade anatomy, explaining the difference in teeth, kerf thickness, and coatings are designed to impact the cut. He describes the variations in tooth geometry and how the teeth are cut in various patterns for specific types of cuts and materials. Nathan shares his advice on picking the best table saw blade while sticking to your budget. Then, Ross Trethewey helps a homeowner fix his slow WiFi. The family has had problems with their WiFi since they moved in. They cannot stream movies on their television in the basement, and sometimes even emails are slow to send. Ross sees a ton of similar complaints from other homeowners. Finding the issue can be tricky since you can’t see a WiFi network’s physical problem. Ross demonstrates a step-by-step approach to diagnose a WiFi problem and determine how to fix it. After checking the wiring and the modem location, Ross shows how to check the Internet speed. He finds that the WiFi signal gets weak in the basement and top floor, but he has a solution. Ross introduces the homeowner to a mesh network, a distributed router system where you place WiFi routers strategically around your house to strengthen the WiFi connectivity and increase coverage. Afterward, the family has a strong WiFi signal throughout their home, allowing them to send emails and stream their favorite home improvement show. After, Richard Trethewey visits a 1950s ranch house to help a homeowner replace his tub drain. The drain is rusted, and the stop can’t be used to fill the tub. The homeowners have done some repairs and upgrades themselves but were nervous to touch the tub drain because they don’t want to mess with water. Richard assures that replacing a drain is a straightforward project, as long as you have reasonable access underneath the drain and everything is correctly sealed. Luckily, the drain is easily accessible from the basement, so the homeowner and Richard get to work. Richard lays out a mockup version of what he’ll be installing and demonstrates what each piece will do. Together they remove the old drain and install the new one.
