Cheers guys.
I'm almost finished. I've done the back of the guitar including markings for where the bevel/carve starts. The only thing I have left to do is finish the headstock, mark the tuner locations and draw the line for where the carve starts on the top. BC Rich actually only made these carved top models for a very brief period. Most of the Eagles made were flat top with a bevel around the edge a bit like an SG.
Happy to send you guys the file when it's finished if you want it.
