stack and taper

(1/10) > >>

harry 62:
I need some help on stack. I am going to build a mid 40s 60 " one piece recurve. I would normally use .260 but end with .002 taper. I have been reading on here about using .001 or parallel for a more stabil limb at lighter poundage.The bow will be semi static the hook without the extra tip reinforcement. 22" riser limbs tapered from fadeout to tip.

bwatters:
The latest off my form is 0.245" stack 0.001" taper with 22" riser gave 40 pretty much spot on.

I think 0.255" or so should get you in the ball park.

Kirkll:
I can’t help you on stack height. The shape of your limb, and limb pad angle will effect your stack height too.

But… the .001 taper rate will help out torsional stability a lot. Once you get below 40# go to a parallel, and 30# a reverse taper. Nothing worse than building light weight limbs that want to go sideways just looking at them wrong. Kirk

Crooked Stic:
Same form just changing taper 255 might be a bit heavy and use some stable core to.

harry 62:
do you count the .015 stable core in your stack or is it stiffer like carbon. I am having trouble with going from .002 to.001 making the middle and tip .020 and .030 thicker. Better a little heavy than too light.
