Mimosa

Selfbowman:
Hamish that sounds about right on width. And 66-69” on length if you have  a stave that long. Good luck with it Jim I’m watching.

Hamish:
In the back of my mind I'm still thinking, if Badger couldn't get a good bow out of it, it probably isn't going to make a good bow.
I have used Acacia Melanoxylon, which is supposed to be similar in properties to Mimosa(but looks more like Koa). You can make a bow out of it, but it was liable to chrysalling. That one was about 2" wide or little less. A 3" wide pyramid bow would probably be a little safer, in tension and compression. That design works well in many poor, otherwise marginal bow woods.

sleek:
Mimosa seems to have a very low density. Running it through the bow program I built, you will need  67.43 sq inches of wood in the bending section to hold up against set.

Mo_coon-catcher:
I wonder how it would do as a core in a Trilam with it so low density

I usually make pyramid bows. Plan on 2-1/2" to 3" width at fades. Only thing clearly in the favor of mimosa is that it often has long limb-free sections.

I've made bows from spruce and yellow pine, so I'm hopeful. I also have a stave of tree of heaven, which has little to recommend it. Got to let them dry first. I may try to hurry them a little.
