limb tip design analysis request
medicinewheel:
hey briarbrow! - the limb tip is adapted by the samurai bow and for the overall asymmetrical costruction (in combination with very light-weight limbs) these bows have no exaggerated handshock. it's probably not the kind of bow that gets just everybody excited but you should shoot one to find out.

ps: attached is the pic of one i made the same way, seventy-some pounds at 29", 66"ntn. thisone has not an exaggerated handshock even when shoot with light target arrows.

it's a longbow made using the same sort of core cross section.
Marc St Louis:
No offence SM but that kind of performance would be spectacular and would be setting records at flight shoots. I think Japp went to a flight shoot last fall with some of his bows. No records were broken
tom sawyer:
Marc, I think the catch is that the Yumi is pulled to a very long draw, much farther than 28". I think they pull something like 34-35", I know its back past the person's ear. That'd make a big difference, another 7" of power stroke would be something like 30% more stored energy. So I could believe the speed claimed.
I think the use of mulberry, since it is a lightweight wood, probably mitigates the potential for hand shock.
briarbrow:
Hey Medicinewheel. Is the lack of mass appeal because of a finicky nature or something else?
