What was it made of?

--- Quote from: Badger on April 03, 2019, 08:53:20 am --- I made what I called a hinge bow several years ago with very extreme recurves and reflex, something like 12". The bow was about 4" wide in the bending area which I think was no more than about 8" long up close to the handle. It broke down quickly because of set and hysterisis but in the initial shots it was the fastest bow I had ever seen bar none with a 10 grain per pound arrow. I think it was like 212 fps on the first shot. And dropped with every shot until it stabilized after about a dozen shots. Once it stabilized it had no real performance left but it did confirm what is possible if the right materials were used. Short working areas solve a multitude of design problems with bows. The stored energy was over 125% of peak draw force.

I remember this bow. It was Osage. Steve, you are the only guy to break 200 fps at 10gpp, and hardly anybody even knows it. I think about that design often, trying to figure out how to stop the losses you encountered, then use that in my own short bow design. Probably won't ever hit 200 fps, but i want steady 180s, consistantly between bows. Im close. That bow was insane to see on your thread.
maitus:
I think the limbs will move back exactly the same way as they are pulled back. You can do it slow, moving your hand back from full draw, or fast, relise. The speed depends just from arrow weight. My understanding of gearing is ratio between pulling the limbs back ( straight limb bow) and pushing them together vertically (5 curve bow). If to think, why braced bow have bigger string tension than full drawn bow....and why stringig a bow is easier with bending the limbs, than pressing the tips together (like kids bow), it could explane something.
Its hard to explain what i think in foreign language but i hope you get what i mean :).

This is much easier to do with a computer model however. ;)

Alan, Do you think that a FE type program, such as the bow-simulator that was discussed a while back, would have potential for these type of observations?

Yes, I do believe so. I haven’t spent much time in that program yet, but I believe it has great potental.
