How much working limb

[Mad Max]

What is the minimum length of working limb for a working Recurve ?

[Crooked Stic]

Man thats a loaded question. It will vary with riser length and pad angle wedges taper etc.Where your design optimizes. Kirk of Bigfoot bows has done a ton of research and development. He will help if you ask.

Thanks Stic 
60" NTN, 22" riser, 7 degrees,  1 piece recurve
So I'm at 19" now

Go to your corner Roy

I was going to send you  a Osage Stave.

19 ought to be plenty. 7 degrees is pretty flat.. Got a pic of it.

Ya sure ya wuz....

Is a 22" riser really necessary,  is it not better to have a shorter riser and longer limbs been the same weight, length.  Make for a smoother bow would it not.?

Looks like a radicalized Shakespeare Necedah.

Build it.  Inquiring Bowyers want to know........ without spending our own time and money! 

[Crooked Stic]

That will work fine. Wolf look at some of the TDs with say a 17 in. riser and wedges sticking out each side 3 in.

If wedges take away from working limb,  what is the benefit of having them?

Wedges are required on the butt end of take down limbs to create the fades that are normally part of the riser on one piece bows. That way you don’t create a hinge at the end of the riser.

So, I'm assuming there is a fine line between too short of a wedge and too long? Too short creating the possibility of the hinge and too long subtracting from the amount of working limb? Not trying to hijack the thread but this relates quite a bit to my post the other day.

Lets say you built a TD with no wedges. First off it is gonna be too thin under the bolt to handle the stress. Even if it did handle the stress it would be flexing.
