measure techniques - Halfathumb - 03-06-2022
How do you measure a large inside dimension like on a cabinet checking for square?
Using a standard measuring tape isn't exact. Do you use a helper when the distance is exceeds your reach? Has anyone come up an adjustable jig of some sort?

Make some bar gauges or "pinch sticks" --

Depending upon carcass size or design, this also might work:

I have the Veritas heads and have used them for over a decade or more, that's what you need. Highly recommended.

Admiral is onto it! I bought the Veritas bar gauge heads on a whim about 20 yeras ago when I got tired of always clamping on a binder clip and the clip always seemed to slip.

All great suggestions above. I usually just grab some scrap sticks and square off the ends as in the video Ray posted. If the two sticks are to long to easily hold together, I put a small clamp on them. This is probably the most accurate way to do an inside measurement.

Tape measure for all cross measuring perfectly adequate for me to 1/32"

A pair of brass stair gauges designed to clamp to a square to mark an angle work well to clamp together a pair of rules for use in the same way as the Lee Valley tool.
If you have an old fashioned folding rule with a 6" sliding extension, that's my favorite for internal measurement.

Great idea. Now I have to find them
