Title: Water buffalo and sinew bow?
Post by: BrokenArrow on October 09, 2019, 08:42:47 am

Any thoughts on making a horn bow with just water buffalo horn and sinew? Kind of like a sheephorn bow? Has anyone ever done this and if not why not?
Thanks

I have seen that...
I saw some pics from museum with heavy crossbow with horn / sinew limbs ...

But for the physics sake :
For the composite bow  - the lighter the limb - faster the bow will be. As wood core is lighter as horn - so bow should be faster.
Second - the core does close to nothing in the bending - and only skin of the bow does. Sinew layer for tension and horn layer for compresion forces.
Core is only for stability of the whole composite structure.

For example: Modern recurve competition bows use carbon limbs with rigid foam core (lighter than wood), rather than full carbon limb.
