core tuff question please help

[Werewolf]

If i add a layer of core tuff to my limb stack is the amount i can reduce my wood laminations proportional to the thickness of my core tuff or do i need to reduce the amount of wood laminations to a greater extent?
any help would be appreciated

I've only used it once, and on an experimental bow. So I have nothing except someone told me it made no extra weight on their bows.

I count the core tuff in the center the same as wood in stack thickness.

I follow the same procedure as Pathfinder but use stabil-kore which is similar I am told.

I am with Pago.  I have used core tuff a couple times and I think it adds unneeded weight to the limb. I much prefer the lighter, thinner stable core that kustom king sells. Regardless of what I use, I count it all the same as wood.

I think ALL fiberglass adds unneeded weight to the limbs

Probably a dumb question,but what is the advantage of either one over a wood core ?  

[Pago]

Granted it was due to a mistake but I have a 1" wide recurve limb that shows no bad stability issues in a 65# bow.  I don't think that is possible with a wood core.  I can't prove it empirically but I believe it adds both torsional and lateral stability.

My understanding is that uniweft helps with stability like stabil core.  Both have strands running running across the length of the glass.  I think coretuff in unidirectional and would have less affect on the limbs stability.  It would probably add only the same amount of stability that a like thickness you usual core material would add.  I must admit I have never used coretuff or stabil core in a limb but, have used uniweft a few times.  In the future I would go will go with stbil core to reduce weight.  I have always figured the uniweft the same as wood with no adjustment to stack height and came out fine.

ok thank you guys

"looks".  You can add a colored stripe down the middle of the limb.
