Haven’t posted a project in some time so here is one of my latest.
This is my take on a polyurethane string short scale bass.
Neck – Honduran Mahogany Through neck
Wings – Spalted Maple burl
Headstock veneer – Spalted Maple burl
Nut – 1 13/16
Fret Board – Rosewood
Frets – 22 Medium Jumbo
Bridge – Rosewood with Maple burl spacer
Pickup – Acoustic bass piezo
Machine heads – Hipshot custom ultralight
Strings – polyurethane
Finish – Tru Oil Still needs to be rubbed out and waxed
As you can see in the pictures the strings are extra long at the tuners. I’m still in the process of getting them to tune so I don’t want to cut them until it will stay in tune. The maker of the strings says it can take up to three weeks for the strings to stop stretching and stay in tune.
I am happy with the body shape but have to work out some design problems. For example the string spacing was supposed to be 19mm and the holes are drilled for that spacing. However, that was based on the measurement of the strings from center to center. Having never worked with the polyurethane strings I didn’t realize that they would have to be stretched so far to tune them that the string diameter was almost half when tuned.
Any design help is appreciated.
