Old Recurve Riser "Can this be done"?

[CJ Pearson]

I have a recurve that a friend built back in 2000. This grip fits my hand like a glove. Limbs however have a little twist in them and I believe this is probably due to the string grooves not being even.
I know that this is a long shot but does anyone know of a bowyer that could make a new set of limbs for this riser? Also, here is another concern. Riser is a solid piece of Zebra wood. I have recently been told that Zebra wood over time comes apart. Does anyone know if this is true or not? I do not want to waste any time or money for limbs being made only to have the riser fail. Any help would be greatly appreciated.
Thanks

Don't really have an answer to you questions, but here is another option.  

Many bowyers will copy a grip that you like on their bow.  You could send that riser to be copied.  I would think it might be a more cost effective option than a one off set of limbs.

Good point Hermon, I've thought about that but just not pulled the trigger on it yet.

CJ, A little twist due to uneven string grooves might be fixed by evening up the grooves.
1000's of bows have been made from zebrawood. Many from the early sixties are still working fine, and I have never heard of zebrawood just all of a sudden coming apart.
somethings to think about.

I have a 60's model Pearson Hunter bow with a zebra riser that I replaced the limbs on and it shoots fine but I was not out any labor, so it was doable for me. The expense of having the limbs replaced would be more than the bow would be worth afterwards.
