Looks very nice, Josh. Fun to see you post up.
I've done two of these types of bows from Osage staves. The second just needs a little more scraping. I'm not convinced, myself, that there is much advantage when it's being "carved out" from a stave. I wonder if the more sapling types of bows that have some natural curved contour on both the back and the belly flatten out more at draw and give the advantage? Dunno...
But, looks good. Wishing you well.
