The next important hand tool for the woodworker is an accurate tape measure. Get a retractable one that is at least 25 feet long. Any longer than that, and you start having problems getting it to roll back up. Since measurements on large scale projects can be very susceptible to even the most minute measurement variations, you’ll want to make sure the “hook” or tab at the end of the is firmly attached, with no give. When they get loose, you’ll have as much as 1/8” variation in your measurements. This can add up to some severe accuracy problems in the long run.
Just a little nitpick on the tape measure blurb. The hook should not be completely tight. It should move in and out about a 1/16th or the thickness of the hook. This way you get an accurate measurement whether you hook a part to measure or bump up to it. If you want more accurate measurements with a tape measure, “burn” an inch instead of hooking or bumping the part. Just line up what you want to measure with the 1″ mark and subtract that inch from the final measurement.
