Title: Why Revers Taper Lams?
Post by: Appalachian Hillbilly on December 27, 2021, 06:13:57 PM
In the Bingham pronounced take down long bow, why do they use a Taper AND a Reverse taper? Why not parallels then?

They don’t have any parallels all they have are tapers

According to their websight, the "Pronounced TakeDown Long bow is:

Glass
Taper
Parallel
Wedge
Reverse taper
Glass

In that order?

The small end of the reverse can bend around the wedge easier.

Thats about the best answer I've heard on that...

If you lay down a taper, a parallel and a reverse taper in a stack and measure at both ends and in the middle, you’ll have the thinnest section in the middle. So the tip section maintains strength and speed despite being tapered down to a slimmer shape, spreading the energy along more of the limbs length.  I think.?

My bad…I just did the math then went out to the shop to confirm, and I was ….not correct. ? But it sounded good, at first.  Back to bending around the wedge I guess.  :bigsmyl:

Send Binghams a email and they will tell you why.

A .001 and a reverse .003 make a .002 taper.
That's all I got for a answer

My Treadway bow has reverse tapers in the limbs. Mike built it in 1999.

I need to ask Mike, probably pick his brain some if we go to CTA

Easier to bend at Wedge area and easier to get bend down ramps on the belly side on steep ramped risers on one piece recurves and longbows.

From Binghams

Thanks for your question. It is a long explanation for an email but to cut to the chase, the reverse tapers make sure there is no possibility of gaps at the fadeouts of your riser in your limb.
