@Sonic and Jim
Yep, pretty sure the only answer is the pine has moved more than the ply. I'm a bit worried now that the new pine I have bought is greener than the last lot, so I could be facing the same problem in a about week's time. Oh well, good job its just a hobby that I enjoy.

I think I will take Jim's advice in the future and get some reclaimed wood and try and work with that.

I only have hand tools to build my guitars and leveling off the old body precise enough to take a cap is probably beyond my skills at present so if I do use the old body it will be as it is, which doesn't bother me. Beauty, they say, is in the eye of the beholder. LOL!!

Thanks for the input guys, much appreciated.

Cheers
