This is a Harmony-made Sears Silvertone 1478. This body style was originally called the "Silhouette", and Harmony sold similar models under their own name. Later it became known as the "Bobkat". I can't find a serial number anywhere, and I'm not taking it apart to look for one, so I don't know the exact age of this guitar.
My projects are generally inspired by classic designs, but with a twist. I like to build things like basses on guitar bodies, non-standard scale lengths, and occasionally originals, and experiment with materials, finishes, and electronics. One of my great interests is driving the cost out of luthiery by sourcing parts and materials from the hardware store. I prefer to build more guitars than simply more-expensive guitars.
This photo speaks for itself. I got this nice piece of 1/4" walnut at the local hobby shop. They have lots more like it. Walnut is softer than hard maple - 1010 vs 1450, but otherwise similar in strength - 1.7 vs 1.8. I've read a lot on the internets about walnut fretboards, and come to the conclusion that 90% of it is BS - know-nothings stating their suppositions as facts, or repeating standard luthier nonsense.
