Winter project - Yew Recurve bow
PatM:
The thought in the past seemed to be that the shrinking sinew had the potential to separate the sapwood from the heartwood. Don't know how often that actually happened.
While the backing Grodon is putting on will add protection it does have performance enhancing potential if the bow is drawn far enough to access it.
Bryce:
Gordon i was thinking last night while reading a book on Asiatic bows. would i be correct in assuming your bow is similar to a composite bow?
(composite) (Gordon) (Reference to)
sinew = sinew = tension
------- ------------ ----------------
wood = sapwood = neutral plane
------- ------------ --------------
Horn = Yew heart = Compression
DarkSoul:
Technically, Gordons bow IS a composite; it is composed of wood and sinew - two different materials.
The principles are the same, but the used material is not. The belly resists compression very well, while the back resists tension very well. But that's where the comparison ends. Horn is MUCH better in compression than yew heartwood. You really can't compare an Asian horn/sinew composite to a sinewed yew recurve, IMO. Both are good bows - just not comparable.
Gordon; excellent build along. Very clear way of describing the process, nice photo's and outstanding craftmanship. It's inspiring to see an experienced bowyer at work.

I gotta commend your photography skills too!
Bryce:
i know that horn and yew cannot be comparable, as far a the amount of compression. as to they play a similar role in the construction.
