Here's a project I've been working on. I call it the 5 String Tentone because its 22in scale is between a Tenor guitar and a Baritone Ukulele. I started with an Epiphone Les Paul X-Press. It's tuned dD G B E. I've been using pretty much all SG parts. The pick-up is from an 82 Special II, the Bigsby is a Gibson branded one from a 70s SG and I have tuners from an SG-X that still need to be installed. The main problem I'm having is with the instability of the Bigsby. It has nylon bearings which tend to stick. Does anyone know of replacement bearings of this size are available? I got some modern roller ones but they didn't fit. Any ideas?
