I followed Sam Harpers build along. 1 1/2in wide, and starting 15" from each tip, taper to 1/2" at the tips, and straight thickness taper from 3/4" at the fades to 3/8" at the tips, then rounded the belly corner edges off.
From there, its all in the tillering. I went slow and gizmo'd the heck outta it. Took lots of pics and drew ovals and straight lines to compare where the limb tips were while bow was drawn on the tillering tree. Also checked often to make sure I was scraping evenly, to avoid any limb twist.
Have around 3000 shots through it now, and just one chrysal showed up on the upper limb. Bow has a bit of hand shock, but is pretty fast, I keep the brace low, around 6". I am ready to try some woods other than oak, next bow is gonna be hickory backed bubinga, which I am excited to try.
