Some time ago, I came across an article about the Turturro Turnover Mandolin Ukulele. I was fascinated by it and initially wanted to make a fully electric version with magnetic pickups. I ran into a problem of routing out cavities for pickups on each side, while still keeping the body as thin as possible. Instead I elected to use piezo rods as pickups.
I showed some early pictures of my build to King Uke of The Ukulele Blog. He immediately dubbed it the “Hulberto Turnover”. 🙂
Here is a scan of the original patent drawing. The rest of the patent can be found on Google Patents.
I used the patent drawing as a guide to cut out the body. The wood is cherry.
Both instruments have 13.875 inch scale lengths. I could not find a tailpiece that looked like the original scallop-shell shaped one, so I fabricated one out of aluminum sheet metal.
I gave the body a red mahogany nitrocellulose lacquer finish. The fretboards are rosewood.
The headstock is very crowded with all of those tuners. The ukulele tuners are friction tuners.
A string retainer on each side keeps the strings on the nut.
I could turn this thing over all day long.
See it in action!
