Anyone heard/read anything about this bow?

       :eek:      :confused:

"horizontal curl, like a tape measure"----doesn't that sound suspiciously like Adcock Cross Section?

there will always be someone that thinks everything should be easier. I guess most of us here don't follow that philosiphy.

Very much like the ACS

seems interesting. Would like to see one up close maybe it will be at the world archery festival in vegas. I wonder how it uncurls-Scott

No argument from me. But I bet we see the inevitable..."So what's the difference between shooting this bow, and a "trad" bow that is CNC manufactured using multiple laminations, backed by fiberglass AND powered by a fastflight string..."

Wonder where P&Y would record an animal taken with this bow?

Interesting, it looks like he filed for a patent in 2000 and publication date was in 2003. I did a search and couldn't find any other articles about the bow. I wonder what he is doing with the design now?

From what I can tell the only similarity with the ACS is the cross section.  In the ACS the force-draw is an upward slope, in this guy's design, the force draw curve is a hump, the weight dropping off like a compound.  This would allow the bow to have more stored energy like compound.  It probably won't be as efficient as a compound because the limbs more further.

If the materials in this bow are very durable, this would be an improvement to the compound bow because there would be less moving parts and be able to be stored in a smaller space.

This was my favorite quote from the article:

"But Jenkins, an experienced hunter, said the bows (compounds) leave much to be desired aesthetically because they are so machine-like."  

I thought that was my invention until I heard about ACS.

I had seen the article some time ago.   Doesn't really look "suspiciously" like the Adock patented limb in my eyes.    Be interesting to see if the fellow ever followed up on it any more though.   I'd also be interested to know if this, like many 'modern-developements', hadn't been experimented with before and is now being revisted.

Sounds like an ACS in cross-section but then it's supposed to uncurl or straighten as you draw to decrease draw force. I don't think the ACS "uncurls". I'm no rocket scientist but it seems it would be extremely difficult (if not impossible) to make a limb with the ACS profile flatten during the draw.  
Maybe I'm dumb like that, but I don't think you have to worry about this being the next great thing.

Jed,

My understanding is that this was Fred Bear's first impression of the bow he thought looked like, "The Mackinaw Bridge".

The compound bow was invented in 1928. According to man who ran the Fred Bear Museum in Grayling,Michigan.

So what he is saying is one of his bows my have a peak weight of say 65# and at full draw you would be holding say 40#, interesting. (Just pulling these #'s out of my head as a thought)

Sounds like it might be the inverse of the ACS?

With the curve in the limbs the other way?

Rick ,    I was doing the same as you , INTERESTING mmmmmmmm >>>--------->> sign me up!!!

Jeff, you are probably right. Makes better sense that way.

Again, I'm not a bowyer... but how would you make a limb that changes it's cross sectional shape during the draw? I don't think fiberglass would work. Even if the science were convincing, I'd probably have to see it to believe it. Then I'd probably put it down and grab one of my own.

I thought the limbs were made completely of plastic and they would have to flatten out at the time the draw weight would decrease.

That article was from back in 2004.  It would be interesting to see where his design is at now.
