I've seen the Woodpecker's Gap Gauge (that you can't get any more) and I'd like to make one for my shop. Anybody here make one that you like to use? I'd like to know the math behind it.

If you have a machine shop you could make your own, the graduations are all trigonometry derived. Make a tapered wedge and then mark your graduations. If the wedge has a consistent taper, the graduations will be spaced linear.
I use a Starrett 270 taper gauge that measures from .010 to .150 inches, but this may be too fine a scale for your purposes.
Looking at pictures (My internet is taking a break right now, so I can't watch video) it looks like the width of the fingers match the with of groove at rear. You could use two pieces of 3/4" stock for body, and 1/8" aluminum for the fingers. drill and route body. Using dado blade cut the interlocking fingers in aluminum, and attach to the halves of the body with counter sunk screws, or CA glue. Double stick tape body halves together, and using a standard 1/8" carbide blade, cut groove. Add hardware and be done.
Wouldn't a vernier dial caliper do the same thing?
