backingi a shot in bow
« on: January 15, 2009, 10:31:00 PM »
I am thinking about putting a bamboo backing on a hickory board bow that I built several years ago.  It's 60" ntn, 2" wide to mid limb, tapers to 1/2 " tips.  When I originally tillered it, I didn't get it bending enough in close to the grip, so ended up with stack the last 1-1/2 of my draw.  It shoots fine other than that  (took a doe with it), but don't care for it that much.  It has about 2" of set.  My question is, can it be backed in perry reflex  about 3" and retillered ?  Will it be a dog since the neutal plane has already been established.  It's about 55#@27 now. I'd probably shoot for the same after retillering.  Thanks in advance for any advice.

Generally with bows that have been stressed adding reflex, and boo backing, would over stress it even more. A backing like hickory or elm and a slight Perry reflex might do better. You could also try tempering the belly with the bow on a form that would add reflex.   Kicking the tips up a bit will help with the stack and add a bit more zip but will also stress the already stressed belly.  If you are up for experimentation one of these methods or a combo of these methods might work out for you.
   I think I'd just make another bow and give this one to the kid across the street.     Pat

thanks , I probably don't have enough winter left as I'm working on another bow that I am going to sinew back.  I may do what you said Pat and leave well enough alone.   The time spent on something not really broken could be used on something else.  I'd thought about doing the tips a bit, but it was short to begin with.  thanks

Being that it is short makes it stack easier because of the string angle. By flipping the tips you make a more favorable string angle thus less stack.


That being said, "The time spent on something not really broken could be used for something else."

I was thinking in terms of adding more stress to the remaining working portion of the limb.  If I did flip the tips I would definitely back it also.  One limb has a runout that lifted.  I used super glue on that and it held but don't think I'd want to stress it much more.
Where is Brevard in relation to Stem?  Our pastor is from there.  Got him started in traditional archery when he moved up to Mt..  Killed a w.t. doe the first year he bowhunted.  Last year went with him and hunted on his grandpas farm not far from Stem.  We each killed a deer.  He's hooked on traditional archery.

I don't know where Stem is.  Brevard is west of Asheville and is above where NC, SC and GA come together. South Western NC.
