I noticed this(and thought it was wierd)-
LIGNUM VITAE “Ironwood.” Heartwood is about 1.14, heavier than water. I’ve made one bow from its sapwood, density estimated at .85. A bend test yielded ¼” of set when bent 3” to 38lb. Osage yields about 3.5” at 34lb. A slight thickness adjustment would have them testing the same. An osage-design bow took near zero set. A heartwood bow might best be 20% narrower than Osage.
Something is better and stronger than Osage? Never thought this would be possible.
I seriously thought osage was the BEST bow wood in the world.
