Sometimes when you're working on a project and you need both hands. One to hold the pieces together and the other to tighten the screws, you might find that difficult unless you have a set of screwdrivers that are magnetized.
When you're working with a circular saw and a four by four block of wood, the saw blade is not going to cut completely through the wood. So try this tip. Take a speed square and a pencil and on your mark draw a straight line across the top of the board. Mark all four sides and continue the line all the way around the board. Now when it comes time to cut, all you have to do is follow your lines and you will end up with the perfect cut.
Does this sound like your home? You want to keep the carpet looking nice so you require the kids to remove their shoes when they come into the house. Lo and behold you finally get them into the habit. Unfortunately a new habit crops up. The kids kick off the shoes at the very front door or nearest hallway or by the garage and there you have a large lumpy pile of shoes toppled on top of each other.
