Ok...need help...difficult to admit as a typical man...
I glued up and shaped a R/D longbow: Leopard wood and zebrawood with a cedar core under clear glass.
Looks nice.
I got shallow string groves cut and a short string on it. Bends nice, except one limb looks like it is being pulled to the side by almost an inch. The limb isn't twisting, it's just pulled sideways.
I realize this would be easier with pictures, but I'll try to describe:
With the belly side up and sighting down the string, It looks like the limb tip is being pulled 1" left of where it should be and is therefore not in line with the center of the riser ot other limb tip.
In this view what side of the limb should I sand?
I want to fix this before I finish the string groves (which are all of even depth, btw.).
I had this problem on anther bow and I fixed it, but I can't remember how...
Suggestions?

brett if you have a set of calipers you could graduate the length of the limb and compare each side of the limb in thickness. I did this last night
on a reflexed hickory bow that had gotten a little uneven in thickness. I just mark the high side
as long as it is high and go back and take off wood there. just an idea. it worked for me and it bends a lot better now.
Brent,
I'm not sure I understand...
Are you referring to thickness belly to back or from each edge of the limb to the centerline?
This bow is glass back and belly with all parallel laminations. So, belly to back doesn't vary.
More Thoughts?
Brett
Brett,
I was thinking all wood bow and scraping the belly.
I havent done a fiberglass bow before. good luck!
Here is a picture I found that may help. I'm not sure where I found it but I thought it may come in handy one day.

That picture is worth a thousand words right there. Chad
An inch is a lot? Is the bow straight when unstrung?
That is a great diagram. I wish that I had had that when I was making lam bows.-Thanks
Thanks for the photo.
The limbs are completely in line when unstrung...
The R/D shape makes the limbs nearly straight from riser to tip (side profile) when braced.
Thanks,
Brett
