Hey Guys,
I've been looking at a mulberry branch stave a guy gave me a year or so ago. It was only about 3 1/2" in diameter and had two huge rings of sapwood. the rings were about 1/2' thick each. Oh ya... that only left about 1 1/2" of heart wood. I had split it in half as soon as I got it and put it inside the house to dry. I did a lot of research and found that bows have been made out of sapwood only. Most of them was reported to have pretty good cast, except I found one that Pearly made was a dog. But I went ahead and took off the bark, not many but a few small pin knots and cut the profile out. Pat B has always said 10 -15% more than osage. So, I made the fades 2" wide out 10" and then tapered to within 9" of the tips to 3/4" wide, the last 9" to the tip I want to make really thin and stiff. The handle is 4" with 1 1/2" fades , ntn is 64". I also put about 3" of reflex in it.
Well I cut the thickness out on my band saw and started floor tillering. I learned on the last couple of bows to do as much floor tillering as possible. I use a push/pull stringing method every time I string a bow and I think that has help me get the feel of floor tillering to within 5-10 pounds of my target weight, 50#. Finished it up on the tree pretty quickly.
Man this bow is scary light in the hand compared to the osage that I have been working with. Every time I pulled that thing back I was expecting it to explode!! but it hasn't yet. No heart wood except in the handle. 100% of the working limb is sapwood. This wood is much softer to work with than osage or hickory. The only thing I have found that I don't like about it is the creamy color of the sapwood. I'll probably stain it when I'm done. I've been wanting a dark colored hunting bow.
Shot it 50 times tonight and WOW is it snappy. I still flinch every time I pull it back.... it is so light in the hand and no hand shock. I can't believe it, Hope it holds up.
OH..... pics are coming, Man I haven't said this much in a long time. I'm just fired up with this mulberry stuff.
