According to this book Electric Guitar and Bass Design by Leonardo Lospennato, my measurements are pretty close. “If heel is too thin, it will affect sustain and weaken the joint; too thick, and the guitar be too heavy and beefy”
Book Recommendations:
Heel thickness no less than 7/8″ (0.875″) mines at .954″ but thinner closer to top of heel because it is contoured a little bit
Guitar top to fretboard HAS to be close to 3/8″(0.375″) mines at 0.44627 – 0.055 = 0.39127″
Neck Pocket depth ~ 5/8″ (0.625″) mines at .546
