A new type of bow design

[Myles Riley]

I turned an old children’s compound bow into a compact lever bow. Introducing the "Clever" bow.
The draw is 28 inches, and the draw weight is around 60 lb. The levers are tent stakes I bought off Amazon for $28, the string is D loop string, those silver things on the levers are 1/16" cable clamps from a hardware store, and the bow is from a Bear Sun Bear youth compound bow. The brace height is 6.5 inches, and the overall length is 35 to 37 inches, depending on how I brace it. It weighs 1.75 pounds. Very smooth draw. Hauntingly quiet when I shoot it. It shoots a 525 grain arrow 138fps, generating 19.98 foot pounds of kinetic energy. So this gives you the smooth draw of a longer traditional bow with the compactness of a compound bow. At only three feet long, this thing is very easy to carry in the woods. The last two pictures show the original bow next to mine.

Sort of reminds me of the Oneida screaming eagle bows... Good luck with the project.

Pretty neat. Get some safety glasses next time at the hardware store for when those zip ties fail and be safe.

Yep, I agree with both of the above! Reminds me kinda of an Oneida bow. Definitely get some safety glasses on!!!

Oh boy, missed that the bow string is an o-ring held on my zip ties... but hey, proof of concept to improve off of, but I would roll with a paintball mask or something... can see that o-ring chipping some teeth if it lets loose.

The zip ties don’t bear any of the load. They simply keep the o ring from slipping off of the end. The ring is what bears the full weight of the draw. Look closely at the bowstring and see that it actually is anchored to the cable clamp base, about four inches below the tip of the spike. So it’s actually a very safe design.

Call me crazy, but when you are full draw, seems the only thing really keeping those o-rings on is the zip ties...

Yes, the zip ties hold the o rings on, but the o rings would have to shear through a quarter inch of titanium at the top of the spikes, since the direction of force is perpendicular to the surface of the spikes. The zip ties simply hold the ring in place. Rest assured the o ring is what bears the weight. The bow string isn’t connected to the ring, it just passes through it, and it runs back down the inside of the spikes, where it attaches further down. That’s where the string exerts it’s force, not at the top.

Like your creativity. Keep thinking outside the box.

Awesome idea! It looks like the stakes would clank against the limb tips but I guess not

That is some really interesting design. Very cool concept

Not bad

 

[ozyclint]

so the cable holding the end of the levers is inline with the string and fouls the arrow path?

might be best to keep the string to stake angle circled in red under 90 degrees. as in trad bows when that angle exceeds 90 degrees you get stacking.
