Ron- I just had a look at the pics on eBay. Since the body is laminated from thin pieces not just two halves as I had originaly envisioned,it may be that the seperated glue joint was just "glue starved " from the begining.
There may be enough bare wood in there so that your plan would work.I guess I'd drill more than one injection hole.I sometimes use a thin blade from a feeler gauge to spread glue into a joint.
I'd also test the clamping to see how much pressure is needed.There is a risk of clamp-denting the guitar.
If this gule-up doesn't hold then I'd saw, rout or carve out the joint to expose bare wood and fill with thickened epoxy.[This message was edited by Mark Vinbury on 18 May 2006 at 07:20 AM.]
