On certain projects, you may be required to work with brass screws. While the brass results in an attractive finished project, it is a soft metal that can easily be scratched or damaged. The solution is to use your drill to create a pilot hole, then drive a regular steel screw of identical size into the hole. After the hold is created, remove the steel screw and replace it with the brass one.
If your extension cord gets tangled up, don’t pull on the ends. Instead, gently loosen all the tighter snarls in the middle until them become larger loops that can easily be untangled. A way to avoid tangles is to use a retractable cord reel. It will let you reel out only the amount of cord you need, then quickly reel it back when you’re done.
