Saxton Pope had said a walnut heart with the sapwood on the back made a pretty decent bow. I cut a 6” walnut a couple weeks ago but it has virtually no heartwood. Just for giggles I roughed a blank out to let it dry faster. 6’ long, 2” wide and 1-1/2” thick. Set it up in the rafters of the shed.
Is this decent bow material? What about heat treat/ fire harden?
