Medieval Compound 240#@28"

I guess we will never know if it was a failed experiment or actually made it to the production line.

Looking at the picture, I cannot see what part of this machine is supposed to store the energy.

Without seeing even some photos of the purported original artefact, or references to extant literature mentioning such a device, I feel safe in being skeptical at this stage.

I'll go out on a limb here - Male Bovine Droppings !!!

Then again if you read it on the Net it must be true :biggrin: They had the technology, look at the mechanical spanning devices used on some crossbows for example. Its not to long a Bow to draw that a thinker could have adapted it one way or the other ? I wanna believe for ALL the wrong reasons :lol: :lol:

Looking at the picture there doesn't seem to be a lot to go on, however, making an educated guess about where the energy is stored, I would say most likely in the pulley just below the users right hand. It's not a far stretch of the imagination to see that the pulley would turn upon pulling the string and then spin quickly upon release. But that's just a guess.

I wouldn't dismiss this article out of hand just because it doesn't look good or because it goes against what we as traditional archers believe. If there is evidence to suggest this compound bow is an actual invention by our ancestors, then there is nothing we can do to change that.

I for one will not lose faith in my recurve or longbow just because it's possible the English toyed around with the idea of using training wheels on a bow.

I understand how the cams work. What I'm struggling to see is what part of it yields to applied force then returns to its former shape.

In a wood bow, the limbs bend quite a way to store energy. In a modern compound, the limbs bend a little bit and the cams allow for large string movement.

I can't see which part of this contraption is supposed to bend and store energy, that the cams help to take advantage of. From the look of it, the only way I can see it would work is if the string were an elastic band.
