Mimosa

[Jim Davis]

I've been  casting a baleful eye at an 8" mimosa by my creek for a dozen years. Cut it yesterday and split some staves from it. It was amazingly easy to split.

No idea whether this wood will make a bow, but when it is dry, I'll find out. Looks interesting.

Hmm, we’ve got a few in our yard. So I’m curious to see how it works for you.

   I have only done one and I would say it is not a suitable bow wood. But! I hope you prove me wrong. I found the wood to be light and not very strong in tension and it splintered very easily.

Never used it but always exciting to use a new kind of wood, if anyone can pull it of you can. Look forward to seeing it in the works. Pappy

Mimosa, Acacia Dealbata, average dried weight: 40.9 lbs/ft3 (655 kg/m3).  Haven't used it either. I do know that many acacia trees make good bows. If in doubt start at 2" wide limbs, for a 40-50lbs bow and see what happens from there.

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.

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.
