Using Hammers for Rough Measurements

You don't need a tape measure to take rough measurements—use your hammer instead. Measure exactly 1/2 inch from the head of the hammer and mark the handle with a piece of colored electrical tape. Place another piece of tape 6 or 8 inches from the head. If you have a long-handled framing hammer, you'll be able to add a tape stripe at 16 inches.

This timesaving tip is especially effective when doing repetitive nailing, such as driving evenly spaced nails along the edge of a plywood sheet.
