Actually I can see why they did it this way. If you think of how difficult it is to glue up and try and get those wings aligned properly at a different thickness, it kind of makes sense. They could have even tapered the wings and routed everything before gluing it up. The V groove ensures that the wings go on square and flush. They would just have to have a jig to make sure they were aligned front to back at the proper place. I believe the reason for most of the bursted paint jobs is to hide joint conditions. The same is true with the Firebirds. Those joints would be completely obscured by the dark burst, so I'm pretty sure it wasn't a feature. In a production environment it would be a pretty cheap prospect to make shaper tools to do that and it would save time in glue up and clamping. Unfortunately it is an expensive prospect to someone making one guitar. ;-) That bit was about $120. I'm hoping to make a few more. I'd like to make a replica of a '64 Firebird V with the correct wood at some point. This is just a hobby for me and I make guitars for friends and people I meet here as a way to get better at the craft and charge enough to pay for some cool tools etc. I'd never be able to afford the cool tools if I did this for a living but some day I may be able to retire into it as my products and production times improve. ;-) Thanks.
