Adding weight to Laminated bow?

[grouse11]

I am not really sure about this but figured I would ask. I am interested in a vintage bow that is not necessarily super valuable but fairly rare which is why I want to add weight instead of buying a heavier one.

Is there any way to add draw weight to a laminated bow. Could I take the limb tips off and glue another piece of fiberglass on the back of the bow? is there some sort of backing other than sinew that would increase the weight? I would like to add at least 5 pounds if that is possibly.

Thanks in advance,
Mark C.

assuming the old bow is in good shape, I think you could cut off the limb tips and make new ones. the shorter bow may then need to have the limbs retapered. I would wait for the pros to  reply  before you start cutting

The problem with cutting it shorter is that it is a herters 46" bow. Don't know if I want to make that any shorter

What is the weight now?  What are you wanting to hunt with it?

I ground some glass to .020 for somebody to do just that, I think it was Sharp Shooter. I don't know what kind of weight gain he got, but I think on a 56" recurve it would be a lot....

the weight now is 40. even if it took it up in weight anywhere from 55-60 i could make it work. Thanks for all of the help so far.

well, my eucalyptus bow was not heavy enough so i made,
2 layers of fiber glass and polyester addition on both sides, belly and back.

it doubled the weight! not kidding.

I have glued an extra layer of glass to the belly side of a recurve to increase the weight. It worked really well, but I was able to put it back in the form for the glue up, I dont think I would try it with c-clamps.

5 lbs of glass would be so thin as to be unusable.  Wish I could help but other than cutting an inch off each end I can't think of a simple solution.
