I've been wanting to post this for a while. Without a doubt this is one of the most challenging projects I've worked on.
The task: Put this vintage Supro neck on this new Eastwood Supro style guitar body. Install the vintage electronics and bridge. Use all original parts regardless of condition. Make it work.
The challenge: They don't fit together. At all. By any means.
First things first. The old neck is designed to be on top of the body, not in a heel joint like the modern body. I needed to fill the neck pocket and ensure the neck had a proper angle to line up with the bridge (which was really high as you can see)!
Created a plug to cradle the neck, which later would be sprayed black to match the neck.
Problem #2: Somehow attach the neck to the body. Really long screws? lol Cannot use existing screw holes because they DON"T LINE UP. They would screw right into the side of the neck! So we create new ones with the drill press. Deeper into the body to facilitate the screws. 4 screws to insure stability. But with a very narrow mounting base on the neck, it had to be laid out narrow as pictured. This way, I can still use the chrome neck plate over top, covering up the modification.
Problem #3: The pickups don't fit.
As you can see, I had to block-fill the pickup cavities in order to mount the pickups. The old pickup mounting ring actually sit on top of the guitar. So a quick mod was to just fill it with some shop wood so that the pickup mounting rings would have something to screw into.
Problem #4: The neck pickup mounting plate is broken, has no base.
Riiiiight. Not so bad. Used some epoxy filled onto one side, when it dries it's hard like plastic so I can screw it down and it will be solid. It also will keep the mounting base together since it was totally deteriorating! On the other side also missing plastic at it's base, picture #2, there was some plastic left I could work with to mount the ring to the wood base. Just enough. What an ordeal!
Problem #5: The pickguard doesn't fit on the body.
Oh dear. The original pickguard is a tad small for this body, but I made it fit best possible. It took quite a bit of realigning until I was happy with where it was sitting. It just barely covered the control cavity, but over all I fulfilled the request of the owner and made it work for a very modest bill-out.
