Winter project - Yew Recurve bow
Onebowonder:
Perhaps I am misunderstanding the whole question. What does "the neutral plane" mean? Isn't it largely like a core in a tri-lam? Meaning it does much less or no work and therefore does not have to have the same high end material characteristics as the working portions of the limb. That's how I had envisioned the question. Hope that helps. If not I guess I'll have to go back to a clothes line and a PVC pipe... :embarassed:
Prarie Bowyer:
I mean the radius of the flipped tip.
Keenan:
Onebowonder,
The neutral plain of a bow is an imaginary line or better stated " A place" where the wood is not in compression or tension. It is not a measurable amount but rather a place where everything above (towards the back) is under tension and everything below (towards the belly of the bow) is under compression. The mear shape or the limb can change where that point is. Example Imagine if the limb had the shape of a triangle, with the point being the top or back of the bow. The neutral point would be very close to the bottom because of greater surface area. If inverted. with the flat as the back of the bow and the point at the bottom The neutral plain would sit much higher and sure overpower and crush the bottom. If the limb profile is that of a rectangle the forces would be closer to the center and better distributed. Hope that makes sense.
Gordon. Sorry to clutter up this great buildalong. However it is great discussion for our learning.
Bryce:
I know the reason why I do things. So am I correct when saying gordons sinew backing is more for protection? Very beautiful bow by the way Gordon. Like always ;D
Gordon:
Yes, protection - definitely.
