how do you doo it?
Oh gosh, it's pretty long winded... But, since you asked...
You need a ruler, tape measure, calculator and a set of calipers. (My calipers don't reach the spine, so can't measure the whole thing with that)
(1) First off, measure the camber of the bat face. Ideal if you have a GM, as they tell you anyways, but if the camber is unknown, get a measuring tape (The floppy ones used for measuring clothes etc) and put it across the toe from edge to edge. This is so you can see the camber shape. Then measure the depth of the camber, and note it down.
(2) Find the spine swell position, and measure the size of the edge (in mm) there and note it down. (Will be different from the edge swell if you have offset edges)
(3) Then from that exact point and edge, get a ruler and measure the distance between the back edge and spine. Note that down too in millimetres.
(4) Finally, measure the width of the bat, half that value and note it down.
Get a calculator, and square the value (3) and subtract the square of value (4). Find the square root of the answer given, then add values (1) and (2).
It's pretty long winded, but it works for me. I always get it incorrect when judging by eye, and my desk is such a mess that I can't do the methods mentioned above.
Because you're calculating it though, you have to be pretty accurate with the measurements! Found out my GM actually has a spine height of 58.5mm instead of 61mm, as advertised... I'm very disappointed, to say the least!
