Bows / Re: Black locusts bow

Jim it’s at 8 present according to my moisture meter but it could be as high as 8.4 according to my meter chart. Do some math for me and compare the loss in weight and the difference between 10 and 8 percent moisture content.

Just for fun, I weighed  a 44# Osage bow of similar dimensions. 31.5 oz.

Arrows / Re: Quiver, by request

I really like woven quivers, they are totally durable and pretty. I have not figured out a great way to quiet them though. I usually stuff a tinder bundle in the bottom, or wood shavings. And sometimes I've sewed or glued on some buckskin or fur strips around the rim. That seems to help, otherwise they are super scratchy, especially the ash one.
Thanks!

That's good to hear, I was worried they were too rounded or broad. Thank you!

Bows / Re: The best shape for a reflexed bow?
« Last post by bjrogg on December 08, 2025, 06:19:39 am »
I do think this is an interesting question.

My thinking that the one with all the reflex in the handle has the most stored energy is that “all the reflex is in the handle”.

Therefore all the working limb is able to use this reflex.

I have know idea if that is correct. It just seems to make sense to me.

But I could be totally wrong. Maybe reflex in a different area is better? Maybe more leverage further out the limbs?

Thanks for post this Tuomo. I have wondered about these profiles myself

Bows / Re: The best shape for a reflexed bow?

I wanted to do a small study on reflex shapes—bow designs that can realistically be built in real life. Even though theory and practice don’t always align, we should remember that there is always theory behind practical results. Yes, the zero set, but it doesn’t matter, because all the bows are similar except for the side profile. The only purpose of this comparison is to examine how different side profiles affect bow performance (10 gr/# -arrow) in theory.

“mmattockx” mentioned the front profile — it’s quite standard, adjusted so that with a 0.008 taper rate the stresses are distributed as evenly as possible along the entire length of the limb. But again, that doesn’t matter here, because the main purpose is to compare how the reflexed side profile affects the performance of a bow.

Regarding energy storage, it’s true that high energy storage does not necessarily mean that a bow will be fast. However, in this comparison the fastest bow has the highest energy storage, and it also has the highest efficiency, and unfortunately it has also the highest strain values.

Remember, the main goal is to compare different models in an idealized situation. How they are actually built in reality is a different matter, and there are many other variables involved, such as stability, material properties, and so on. However, there is still one model (side profile) that clearly outperforms the others (at least in theory...).

So far, one “correct” answer.
