Tools are integral aspects of building or renovating a house. Without tools, you can't do most home improvement projects. Fortunately, Hometalk has your questions about tools covered. There are tons of experts who work with tools, from pros to experienced DIYers. Need information about tools for a project? Ask a question to the community, and a Hometalk member who is familiar with tools will surely help. There's nothing like celebrating a successful project by posting it on Hometalk, and it helps others when you mention which tools you used.
I found some oh-so-cute starfish knobs for my daughter's dresser... only problem, her dresser drawers were too thick and the screw was too short. This video shares how to solve this problem without having to purchase new screws.
If you've never used any of the products from the Kreg Tool Company, stop what your doing and head straight to the closest home improvement store! As we've been renovating our pantry and
building custom cabinets the Kreg Jig Jr has been invaluable! The Kreg jig system is designed to easily make super strong joints using pocket hole screws on just about any woodworking project. We'll take a look at how to use the tool and also offer introduce some other available accessories that Kreg makes that we find pretty useful!
Older power tools were single insulated. The wiring, motor, and switch were insulated from the case, but the case was made of metal. It was able to conduct an electric current. If an
energized component within the tool shorted to the case, the case could become energized. A third wire was added to the plug. This third ground wire was connected to the case of the tool. If an energized component shorted to the case, a large current would flow through the low resistance ground wire and clear the fault (trip the circuit breaker).
Newer power tools are double insulated. The wiring, motor, and switch are insulated. The case is also made of a non-conductive material such as plastic. Many of these newer tools do not need a three conductor plug. They are much safer to use, especially in damp conditions.
Do not use an older metal case tool if the plug only has two prongs. A three conductor plug can be added as a replacement. The third conductor (green) is attached to the case of the tool with a screw. The ground screw is usually colored green. The ground conductor can be tested without disassembling the tool. A multimeter, set to measure resistance, can be connected between the ground prong of the plug and the case of the tool. The resistance should be very low. It is a good idea to use a ground fault protected receptacle with a single insulated tool. A GFCI should be used when any tool is used in a damp location. Check out my GFCI article on my blog.
