A different recurve

[jess stuart]

I enjoy trying something that is new, or at least new to me.  I don't think there is much of anything that hasn't already been tried.  
I saw a picture of a recurve built by Zbow that was very intriguing.  It had a flat spot in the limb, another bowyer referred to it as a correction curve, or a wave.  I was building a form at the time so I attempted to duplicate, the bow.  I am quite sure the original is much better than mine.  It does shoot pretty good, seems quick and very quite.  It is 58" and uses 16" riser and .002 total forward taper.  Here are a few pics, I think the style is worth further exploration.  Let me know what you think?

that looks real close. Nice job experimenting. I love teying something new as well.

Looks interesting.  There probably is something to it as far as performance,but I'm no engineer.  Black Swan is making that new bow with wavey limbs.

Nice looking!

[4est trekker]

Great looking bow.        Can you tell me what the correction curve does?  Thanks for sharing!

[kennym]

Nice, Jess,

The limb almost looks like a regular curve at full draw,so it must be doing something.

Nice bow, Jess. The full draw pic looks really good.  The flat spots do look different but if no one experiments we wouldn't be where we are today.
Good job.

Nice Jess-that really pushes the bend out from the riser-looks like a good experiment. Have you decided on more curve or tip wedges yet?

[jess stuart]

What does the curve do?  I am not really sure yet, as Trux said it does push the curve out towards the tips.  The bow seems to have a very tight string at brace height, more so than some of the other recurves I have built.  The limbs seem extremely stable, which might be due to less recurve or the wave.  It is very quite for a recurve, I shoot three under and recurves are usually a bit on the noisy side.  Trux I will try tip wedges and more curve on the next one.
If anyone has suggestions for taking the style the next step I am all ears.

There is an older gentleman who've I read about that was once the master bowyer for one of the big archery companies.  I think it was Bear he worked and retired from.  Anyway, he started building target bows with 2 or 3 "steps" in the limbs for performance and possibly stability.  Last I saw his bows were commanding a very high dollar from the target archery crowd.  I saw a used on being offered for $1,200.00 and heard the new ones may be nearly 10X's that amount.
Wish I could remember his name.

I think you mean either
Bill Stewart or Dickie Robertson

"Multi cam" limb design was one name that went by

[bjansen]

Very nice Jess....I think it looks excellent and agree I think we should experiment more on this.  For whatever reason (and it must have been I saw it elsewhere), I was thinking of  doing this on the next recurve form I build.  When I get to it, I will post pics and any data I gather as well.  

I really like the look of it and it opens up very nice.

Not the prettiest bows....   :confused:

Nice job, Jess ! I saw a recurve with some kind of the same type of limbs and was wondering what the reason for this might be. Check this out...

That's a guy in Switzerland that makes them. I have to talk to him about that one of these days.

his name was bill stewart. look on the collectors forum. on the first page you will see a topic called "bear-ied treasure" page 4 of that topic you will find pics of bows with limbs that have a wave to them. the whole topic is interesting as you will see.

Don thanks for reminding me of Bill Stewart, I remember seeing pictures of his multi cam bows in the old magazines.  Wow that brings back memories.  Funny at the time I thought they were very ugly, and now I build one with a few resemblances to them.  I guess what goes around does in fact come around.  I will check it out, thanks for pointing it out.

Looks similar to jack kempfs Raven model. If you had a little more curve in it like David said.  Jess your on to something here keep tinkering.   I'm waiting on my new Kempf bows to get here myself.

Nice Job Jess!!!  I don't see the resemblance to the Stewart though. I like yours much better but then I like a nice clean flow. The design is very , very close to my new Talon 11 limb but I have wedged it into a static. You certainly have great string angle now though.

My personal experience is that with less hook the bow is smoother to pull but not quite as quiet. My tight curved Talon one is as quiet as a long bow where the one similar to your limb is a super quiet recurve. (grin) hope that makes sense.

The nice thing about working it out like this is that you eliminate a lot of r @ d costs and time. Good Job.  God bless you, Steve

Cooks Mtn Archery (Roy Coursey/bowyer) trained & learned under Bill Stewart. About 3 years ago he designed his own Multi-Cam limb. They are a dream to shoot as are his other bows......
