Fiberglass limb width
« on: August 02, 2012, 11:01:00 AM »
What would be the narrowest limb width you could get by with with out causing limb twist issues on a reflex/deflex bow limb design?

I suppose it depends how reflexed/deflexed...and how much the limbs are trapped too.  I would say narrowing the limb itself usually doesnt cause twist, but instead makes variations in the lam stack thickness side to side or errors in the side profiles more impactful, and thus twist will occur.  

On my 60" highly R/D bows (about .370 total butt thickness lam stack, with a .003 taper per inch), I am usually at 1.25" at the fades straight taper to a .500" tip.  I have about 8 degrees of trap on the back of the bow.  I don't go much thinner than that.  

On a very mild r/d bow I would go down to maybe 1.1" at the fades.

On my pronounced d/r-longbows with a taper of 0.004 to 0.006 ( depending of the stack ) i usually make the limbs about 1 1/3" at the fades and 0.4" at the tips. I had to go narrower on a few bows, but i prefer not to go lower that 1.2" at the fades. If the bow is still to strong, you could trap the limbs or sand the glass a bit.

I use a patern to cut all my longbow limb profiles. 1 1/8 at the fade,  3/8 at the tips.

Mine are 1 and 1/16" at the widest point just on the fade.  at the beginning of the limb they are maybe only a couple hundredths over an inch.  If you're careful with the tillering and rough out you can make them very thin.  I had the pleasure of shooting a Fred Anderson Hyak (strong R/D) longbow last weekend with I don't think was wider than an inch at any point in the bow.
