Don't overload extension cords by plugging in appliances that draw a total of more watts than the rating of the cord. Use special, heavy duty extension cords for high wattage appliances such as air conditioners, portable electric heaters, and freezers. When using outdoor tools and appliances, use only extension cords labeled for outdoor use.
Repair leaky faucets promptly; a leaky faucet wastes gallons of water in a short period.
Here's how to disassemble a banister and balusters for refinishing. Using a block, gently separate the banister and newel post just enough to insert the blade of a reciprocating saw. Cut through the bolts and nails to detach the banister. Repeat this process on the opposite end. Then, carefully separate the pieces using the block. Be sure to number each piece for re-assembly later.
You can buy depth stops to attach to drill bits to make blind holes at a certain depth. But for occasional jobs you can gauge depth by using masking tape around the bit at the right depth. Or, as shown, drill through the center of a dowel section, using the bit you need for the hole. Cut the dowel so the exposed bit will be the depth needed for the hole.
