Wild Plum Self bow
JW_Halverson:
I recently had cracks like that pop on a small scrap wood osage bow I was farting around with. It happened when I put tension on the belly attempting to add recurve before I began heating. The limb was thin enough I should have been able to bend it into a circle normally, but it cracked just as the surface began to heat.
My theory as to why this happened is that by bending the wood THEN adding heat the very surface was hot but the underlying wood wasn't and the wood just couldn't take the difference. ALWAYS heat before attempting to bend recurves - that's the lesson I took away.
BTW, I grew up west of Minot. Well, that's a lie. I got bigger. I have yet to grow up. Lemme know if you are ever coming through the Black Hills. I can act as tour guide, fishing guide, or just hang out in the shop and futz around with wood/sinew/rawhide/leather/etc.

I only ended up adding 1 layer. So there are 3 layers total now. And I'm hoping/ thinking the belly is going to be fine under the compression. Plum is a very dense, compresion strong wood. Up there with osage, at least so I've heard and read.
Anyway in a few days we will know haha! And if it's not powerful enough or isnt able to withstand the compression then it's going to become a bison horn bow

Oops I quoted the wrong message! I was trying to quote Dave.
Anyway JW_Halverson I will send you an email when we do for sure! My family has a cabin there in Lead by Deer Mountain. So, we go to the black hills a lot! I love fly fishing in the spearfish canyon and all of the works! It would be awesome to check out your shop and fiddle around with stuff!!
Also it's really cool to find a local bowyer who is into primitive archery! Do you know anyone else from our area?

Welp the bow is done!
It is 43" ntn and has 3 inches of immediate unstrung backset
It ended up with a draw weight of 45lbs at 22in and shoots a 670 grain arrow 125fps! As time goes by it will likely increase a good amount too.
And the whole bow only weighs 8.2oz

Looks good. Good save! I’m surprised you got your sinew dry enough already.
