Yes sir I am trying a new limb design and of course missed the weight light came out 32 lbs. It has worked for me buy just removing .020 from the core and put the twill on the front or if you want really solid front and belly. The only thing is if you use 2 ply witch is .020 you have to put glass under it.
The very first set of limbs I done on a known design was
.020 2 ply twill
.030 core turf
Then bamboo core
.030 core turf
. 020 2 ply twill
Rock solid stable.
I get it from Rosewood shop 65 cents an inch so it is not something cheap. The 2 ply adds no stiffness. They have a 6 ply that you can use on the front that has undirectional added and 2 ply on the belly with no glass. Thinking the Widow carbons are built that way.
Buggs the twill has a finish on one side. Slick and shiny. I suppose you could sand it but not sure it would bee wise.
So, why all that core tuff? Is it to replace the strength of the typical glass?
How about taking the core tuff down to 010 or 015 and adding more wood?
Not critiquing here. I've never been down this path but have been thinking along these lines.
Like I said the 2 ply adds no stiffness. I would imagine you could grind it down to .020 and be okay.
Kirk I got my personal bow layed up just as explained and it not blowed yet. I am thinking all the super curves have 6 ply front 2 ply belly. No idea how durable they are but two high end guys build them.
I have one longbow out with the old Binghams non directional .030 carbon front and belly and they guy has a 31 in. Draw still going strong not even sure how old it is back when I first started building. I told him it would not hold up do it he said.
My thoughts are if you keep the two ply on the belly you be fine.
