Even on rough carpentry projects, such as laying out a wall or partition with a carpenter's square, sharpen your pencil after every six marks. Using a blunt pencil could add as much as an inch to the overall dimensions over about 20 feet. This can throw the entire structure out of whack and make it difficult to fit wallboard, sheathing and other modular materials.
The most common cause of annual mower repairs results from leaving gas or gas-oil mix inside the engine’s tank and carburetor over the winter season. Avoid expensive service shop charges by either 1) running the engine until all gas has been used up, or 2) adding a commercially-available gas stabilizer to the tank before putting the mower away in the fall. A $3 investment may save you a $60 repair bill.
