Max. length?

<< < (7/9) > >>

PatM:
Many of the Manchu style bows were easily of those heavy weights. They were drawn 34-35 inches which is flattered somewhat by a thumbring potentially increasing the drawlength.
 Those qualify as recurves.
Most evidence points to them radically outshooting a longbow when it comes to heavy arrows which isn't really surprising.

 I still see no reason for the arm to "compress". Your arm can't compress because the bones are rigid. It may be collapsing by bending but it's certainly not physically  getting shorter.
 Your rib cage is what would bow under the pressure but again that's only going to happen if your musculature can't brace it to be more rigid.
 I  also am not sure why you feel the bow will pull 180 because of its length. How does length translate to draw weight?

WillS:
Yeah bending due to the compressive forces.  I wasn't exactly suggesting the bone gets shorter  ;).  Either way you view it, the hand comes closer to the body.  Thus the bow comes closer, ergo the draw feels longer.

We're talking about Mary Rose.replicas here.  The longer bows within the collection were projected at having draw weights around 180#.  A long bow doesn't mean a high draw weight. If anything, the shorter you make a bow the heavier it gets.  Hence piking.  However, when discussing accurate replicas of original bows, and somebody mentions making a bow based on the longest bows found which had the heaviest projected poundage, logic leads you to assume the goal draw weight is the same.

PatM:
Maybe if they mentioned an actual replica based on all measurements. I don't know that I would assume all that if a tall guy just requested a bows as long as a known specimen.

adb:
Adult bones won't compress much, but joints will. Bones which are continuously under heavy stress will increase in size. Weight lifters will show increased bone mass and density. Tennis players will show greater bone mass in the arm swinging the racket. No different for archers shooting heavy bows. Skeletons recovered from the Mary Rose showed deformity.
As a bone is placed under longitudinal force it will shorten slightly due to flexing. It can be negligible, or significant, depending on the stress. If a bone is placed under enough stress, obviously, it'll fail and fracture.

AndiE:
Hi

Yes my friend wants a replica of the max. length warbow ever found but he can`t do the 180#.
Are the 180# of the MR bow at 32" or more?

I don`t know why there are always these discussions about muscles and bones associated with warbow shooting, but noone ever mentions the main problem, the ligaments. These are the structurs that are mainly highly stressed or overburdened, and get damaged first if somebody doesn`t know what he is doing or overacts.

Kind regards
Andi
