Say you're building a deck in your yard and have to cut a 10-in. thick post in half. How do you do this with a circular saw with just an 8-in. blade? Make matching straight cuts on opposite sides of the timber. Set the thickness guide to just over half the woods width.
If you’re painting over an old semi-gloss paint, check to see if it has become hard and brittle. Try to pick off a piece from an obscure area with your fingernail. If it chips, it probably needs a light sanding to improve the “tooth” for a new coat of paint.
