So I have been working on a take down osage bow.  It has had it's tricky spots that have required some heat.  I thought I had it all straightened out.  Today I strung it up though to work on the one limb as it's not bending as nicely as the other.  I noticed the string is not centered over the handle.  So I looked at the limbs and the one seems to be stronger on the left side.  So, I started to work that side with a scraper.  Re-string it and look again.  Did this a few times and it still isn't tracking right.  Is this an issue of a strong side of a limb?  Or is there something else I should be looking for?  Thanks for your thoughts.

P.S.  I know pics would help but haven't had a chance to grab any yet.
