Here is a tricky party of the build. Every steel string electric ukulele I have seen uses a Fender Telecaster style bridge. I am build a Gibson style Uke… I want a Gibson SG Tune-a-matic style bridge and tailpiece. Nobody makes them for 4 string instruments. It is fundamental to the design as well. Fenders have straight necks, Gibsons have a slight angle on their necks. It is the way the bridge works that decides which way the neck should be.
I have bought 2 different types of bridge from Hong Kong using ebay. These were cheapest, I can study their design and draw up my own in CAD and see if I can find somewhere to make me some. Screws and fixings I can reuse from the ones I have bought. Here they are, the first set of pictures show the traditional 2 piece bridge. This one looks easiest to replicate, but of course, is 2 pieces and will take up more of the uke body.
This next one is a single piece version. It is more complicated but will save precious space on the face of the uke.
I am going to draw up both and send the drawings along with the parts away for machining.
