I got a start on my first bamboo backed hickory bow.  This is for a long armed friend so it is hoped to be 73" long NTN.
The boo is now thin edged 1 1/2" wide and cut to shape and length.  
The hickory is, also, 1 1/2" wide.  I was thinning the limbs last night to prepare it for the reflex/glue up and, as usual, got a bit carried away.  Now there are portions of it approaching 5/16" thick near mid limb.  My target weight is from 40# to 45#.  Is this limb thickness, or lack there of, too thin to accomplish this once all tillering is done?  If so then it can be piked down for a kid's bow but I was really hoping to use this piece of wood for Jeff.  
Any and all help is greatly appreciated.  
Thanks

TTT, come on men who have so much experience.  I need your help on this on.  Thanks.

Chris,
 I think it would be hard to say, if it will or wont make the weight. I would say continue on!!! See were it ends up, then you will know what needs to be done on the next one.

If it does turn out to light them make it a Tri-Lam and glue another piece of hickory to the belly!

Just my thoughts

If it doesn't make weight, you can always flatten the belly and add on.

I thought of that but after reading another thread the idea that man was going to use was to lam a thin piece to the back with the boo on top of that.  What to do, what to do!!!
Thanks for the suggestions.  These really help.
Christopher
