Bow from green wattle

I have never heard of a bow being made of acacia, specifically green wattle. This tree grows like a weed in various places around the bay area and beyond and is often tall, thin, and straight. You have probably seen it. So I cut one down in Ukiah, CA, my hometown, and made several bows from it, all of them selfbows with an unworked back. From breaking up small pieces of it for firewood, it seems like the outer layer may be more elastic than the rest of the wood. The original log diameter was about 4-5 inches. I think that the fact that the area is very dry may contribute to the strength of the wood as it grew slower than normal, with fairly tight rings. This tree was about 10.

bow #1: 41" long, 12 lbs. at 20". 1 1/4" width, 1/4 " thickness, 3/4 " string follow.
bow #2: 61" long, 23 lbs at 30". 1 1/2" width, 1/2 " thickness, 1 1/2 " string follow.
bow #3: 66" long, 30 lbs at 30". 1 3/4" width, 1/2 " thichness, 1 " string follow.

I don't have a chronometer so I don't know how it compares to other bow woods. These staves may also still be a little wet ( no moisture meter either) so I'm going to test their strength again in a few weeks to see if it has changed at all.

2 months later-- weight has not changed. It's pretty humid here though, 80%, and that has to keep the moisture in the wood up there.
