about 4" remains at each end of each wing. so there's about 8" of dovetail total for each wing. That had been my plan all along though. Had I not routed away that much, the guitar wouldn't be so semi-hollow. more like semi-semi-hollow, ha. if it were a butt joint, you could be concerned, but considering the inate strenght of a dovetail, everything is just chipper. The dovetail looks really nice at the ends where I opened it up and added strips of poplar and ebony inbetween the mahogany too.
*EDIT* I was always under the impression stewmac had a $30 minimum purchase, but maybe not. *EDIT*
