Pat B, i looked at the rings and maybe about 1/4 inch thick, i think i can do that though i never scrape an outer ring from a bow's back before so this would be a little scary for me
bownarra, the wood is local indonesian mahogany, i'm doing an experiment and the bow design will be based on the southwest natives bow with deflexed tips, the scar is on a mid limb off to the side a bit
thanks
