Title: Backing or no backing..?
Post by: bow101 on November 04, 2012, 07:11:10 pm
I need to pull a little more weight on a board bow, "red oak"
Problem is can't get any strips of Boo/Yew or Hickory in my neck of the woods.
I'm on a Poor man's Budget Big Time... :( although I can wait a while...
Silk, denim or any other material will not increase the weight.

Ya ok why not just glue on another strip of oak.!!!!

It's 60" NTN , I'm hoping to get around 40#........ritenow it's pulling about 30# at 25 inches. the bow liimbs are on the slender side less that 1 3/8 ..

Not sure how red oak takes heat, but. Heat treat check tiller. Then flip tips. That may get you some LB's

Pike 2 1/4" off each tip and it'll add a good ten pounds and since you have a short draw it should still be safe. Wait for some one with more experienced to agree with this first since I am still a beginner.

you have a 60" bow with a 24" stiff area, that gives you 36" of working limb, that aint enough, almost half of the bow dont do anything, the handle area is way to big

Thanks bubby, I'll have to remedy the issue.

Is it 24" fade to fade across the handle or is it 24" fade to tip so that each limb is 24" long?  24" for a stiff center is awful long.

that's still  pushing it, standard rule of thumb is double your draw length plus 10%, but hell might as well go for it, if ya got the oak at HD or lowes the probbally have some hard maple that would make a better backer than red oak, but if thats all you can get use it, let us know what happens.

  Back it  with  some  more  Good  red oak!!  some  of  my  best  bows  have  been  white oak backed white oak,,,,a couple  I cut an 1\8th strip  out of the same board and  just flipped the backing over and end for end! now  I was  using  a  very  good  table saw  and  all I needed to do was score the glue surfaces with a hack saw blade like a  toothing plane these  I like to  silk  or  brown paper back   good luck  JeffW

I used a another peice of Red Oak. Have had good success roughing surface with 40-60 grit and even 100 Grit.   ||Perfect mating surfaces and don't over clamp|| Squeezing out all the glue will starve the joint.
I have glued hundreds and hundreds of door parts in the past.
