Inches are not Inches

Any carpenter or woodworker will tell you a 1 by 3 by 8 is none of the above. For some reason this is an accepted practice in lumber. If I was a good writer I’d come up with a deep metaphor about the cumulative effect of shaving quarter inches but I’m not so you’re on your own to figure that out. Fortunately this was just a tray for a midi keyboard.

Measure twice and then measure twice kids.
