Is there someplace one can see the test results from the WTT?
-
WTT?????
-
I know WTF but not WTT. :bigsmyl:
-
Sending you guys links in a pm... You are not allowed to post links of another archery site on here...
The way I understand it, it is like running two hots to a 110v device... It will blow up... :laughing:
-
:thumbsup:
Thanks Rich
-
Any time bud... Hope you didn't mind the joke... :tongue: :)

Walk the Talk. On another site. Bow speed testing out of a shooting machine. 10 and 9 GPP
Was a hot rod class also using lower brace and I think a real skinny string.
If Rich did not get you the link PM me.
-
Not at all...
Just trying to keep the bench running smooth.
-
Stic... Send me a link on the 9gpp... I do not have that one...
-
Stic, send it to me too if you have it.

With a wood bow, if you ask too much of the wood performance drops off quickly. set and loss of high early draw weight and even breakage. loss of arrow speed.
I'm looking over some of these hot rod designs and WTT competition results, and need to ask if similar things happens with some glass bows? Short of catastrophic limb/glass failure, what are the symptoms of core problems associated with designs that ask too much of the materiels?
or from choosing less than top quality core wood?
-
I keep hearing about core failure on glass bows or crushing, but never see anything. :dunno:
If your glass bow breaks at the fades you did not make the fades correct :tongue:
I made a 64" T/D static recurve and the guy draws it to 36"
One just like this.
Limb butt wedges are .036 per inch taper

If you gonna draw that far your wedges probably need to be straight long taper so they will bend some also. Thats what the original reason of a power lam to take the load of the fades. So a long straight taper will do that.

full limb length long?
-
Stic if your talking to me I did not know he was going to draw it that far.
the bow was already made and he wanted it. :thumbsup:

MM,
asked a different way, you do not like to see your bows overdrawn from the design draw length?
If the bow does not break, what do you consider the damage to be? speed loss? set taking?

what is your taper rate on your long wedge from 0" to 3" from the feather end

Who has a fiberglass bow that has set in the limbs?
I will post this pictures again
50" NTN, the nocks are 7-1/2" in front of the grip
just to brace this 50" bow the nock moves 15"

This bow below is at least 20 years old and 70#@28"

No set, no crushing
-
certainly a performer, cool bow. I asked about set etc, on account of your statement about what you consider overdrawing. and the implications for the bow.
BTW, how wide are the limbs on that shorty?
-
He told me it smoked a arrow at 36" draw, I was sure it could be drawn to 32".
It's his bow he can draw it as far as he want to.
1.4 at the widest part
-
1.4 at the widest part
at only 50" and 70#, that's quite impressive!
what is the core wood/materiel?
-
H R Maple

36"draw????? What the hell, is he retired NBA? Or maybe he shoots Yumi style?

I guess there are guys who build bows that like to see some set happen. I believe from what I have read, some Hill styles are probably stressing the core more than someone looking for speed would be happy with.
I'm just trying to establish a stress limit for cores when doing designs....
measure twice, cut once, that sort of thing.
-
will
I think the main thing is fades, alot of guy's fades are .062 at 1" and .130ish at 2", I think for a shorter bow (less than 56") needs thinner and longer fades. less stress at the fades.
That T/D above had .036 butt taper rate with 3-1/2" of fades from the riser most of it bends.
I don't think core wood is a issue, any typical core wood will be fine.
Flem here is the guy that draws 36" + halfseminole
and a link

Using the wingspan to draw length calculator in reverse, this guy would have a 7'8" wingspan for a 36" draw. Not many guys under 7' tall have that much wingspan!
-
No kidding flem is over 7’ with his arms
Roy should know/remember him
He likes horn bows and draws to his ears

We did the first WTT in the mid 2000’s at my friend Steve’s house in California. We had a few in Wisconsin after that. It was a lot of fun and alot of good ideas were shared back then.
