I had a short juniper bow that I put only one layer of sinew. I was overdrawn it and it absolutely exploded. It didn't buckle like a sinew bow usually does. The layer of sinew is what gave. So on short bows I'd recommend at least 1.5 layers of sinew. On longer ones you can do 1 layer. I would say that the fewer layers of sinew you can put on the better because of the weight. That bow that exploded on me was shooting soooo fast 15fps faster than my other bows but it was not enough strength.
@@pierceschmeichel8711 Interesting. It's really hard to pin down what 1 or 1 1/2 or 2 actually means unless you let it dry between layers especially if you wrap and compact. My one layer could easily be the same as someone else's two layers. I actually didn't want to do this subject because it's so general and there's so many exceptions. For example, I've made a lot of heavy osage gullwings with one layer and never had a back give away. It depends on so many things it leaves science in the dust.
@johnjriggsarchery2457 you are exactly right about it being hard to track how much sinew a person is referring to when they say 1 layer. My 1 layer is taking individual strands of sinew and laying them on the bow one at a time, covering the whole surface area of the back of the bow, not overlapping other than to the ends of the sinew strands. Also, I think osage is the reason the single layer works. I should have clarified. I was using juniper, and since it has very poor tension strength, a lot of the tension was going on that sinew. Osage, on the other hand, has amazing tension strength and a very high elastic modulus. So, it is able to take some of that tension away from the sinew.
John, I appreciate the follow up video on this subject matter. Heard some good points I'd like to respond to, but just too long to type out. I will be uploading a response to piggy back off of yours if that is alright. Hopefully not to add to the static of RUclips, but maybe a small amount of usefulness to someone.
@@CrossRootedForge That's the thing, there are so many variables and exceptions and factors that depend on individual techniques and abilities that everything I said can be right or wrong at the same time. It was actually painful to make a video on this subject and I immediately regretted downloading it. Sex, Religion, Politics, and Backing Bows; the four things that will get you into trouble fast.
Thank you. Helping us newbies. See and hear you soon

@johnjriggsarchery2457 Haha! I never was known to entirely play it safe anyways.
Cooool.
