Title: Weird physix... help?
Post by: MoeM on June 26, 2014, 05:39:00 AM
Hey Guys I`m working on my swap bow really under pressure and after getting the 3pc conversion of my hybrid goin and limbs in line I came up with a really nasty spectation;
(   this 1pc (http://tradgang.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=125;t=010364#000000) )
Instead of the .002 total taper I used parallel lams and a plam/wedge 20" long 3/8" to zero.
Now when the bow is braced I can "switch" the remaining reflex between the limbs with a little touch on the reflexed tip...

Have you ever heard of such thing and can even tell me what to do??  

(Help please)

Sorry Moe, I can't follow your description of the problem...

Hm I try one more time;
One limb stays reflexed while the other is already bent deflex, now I can touch one tip softly and they change...

Not better? Well fortunatly I found similar prob an POA;

Sometimes really hard to describe in foreign language...

I had a similar situation with a design I was experimenting with on a long riser td. With that one I was having the same effect unless I ran a high brace. I remedied it with a combination of a shorter riser and a steeper limb pad angle to put more preload on the limbs with a reasonable 6.5" brace. I'm not sure how similar your situation is? What are your specs on the riser now?

With that much deflex & reflex there is a tendency for the limbs to be noodly

What is your brace height?  Sometimes a higher brace will help.

I had a "noodly" tip like you described, and a higher brace helped.  Also, shortening the bow helped and in my case increased performance and shot feel.

Thanks guys, I rised the brace to aimed 8", the tips are still wacky but balanced and stable, hopefully she`ll be good enough to swap soon...

Would a 003/inch taper work better for his design along with a tip wedge??
