@Peter .  Your choice of galvanised wing nuts had me confused.  Thank you for the explanation.

@Irv , as promised please find below some images of the headstock of the wee Beastie. Even with pre-tensioning at the tailpiece, the strings still stretch like billy-oh and the two heaviest have riding turns. This appears to be largely benign. The cable-ties on the E and A tuners have an obvious purpose and take the place of the full top-slot found on most electric bass tuners.

Yes, that's one ugly scarf joint. I may paint the edges of the headstock in the interest of vanity.

Ooh,

I never thought about that. I might share a couple of popular grooves this evening.

@Peter .  The brand name escapes me, but there is a guitar tuner which captures the string end (see photo).  A similar objective could be accomplished by drilling and tapping a centered hole and supply it with a socketed grub screw or similar.

I have been fabricating hydraulically swaged Brass ferrules to secure bundles of horse hair.  This would also prevent the back slipping of your rubber string.  Of course, you would need to make 4 sizes for your instrument.9F282262-F249-4300-8883-24333719C2C5.jpeg

@ELCB - Please be patient; Google is taking its time processing the video.

@Irv - Interesting little device; has it a planetary drive within it?

I had considered using ferrules as terminators for the rubber goods but it would only make sense at the tuning head end (the tailpiece end is stretched manually to pre-tension) and the cable-tie solution so far appears adequate. I may put terminal block cages atop the E and A tuners if I make another (unlikely; this has been fun but I will proceed with a steel-strung bass if I get the bass bug).

@Peter .  Edit on 8/21/20.  It looks to me that gearing is based on a thread ratio which lowers captured string into peg stock.  The tuning machine is called Steinberger or Gibson/Steinberger.

Google is still "processing" my original video, and so I have prepared another using YouTube:

Summer project: U-bass

As  state in the video blurb, I should now go away and learn how to play it...

YouThank you Peter! 

It's been so much fun watching you work on this project! 

It sounds GREAT! 

Have you made a final decision on the type of finish you'll use?

@GregW - I love the sound, personally. It does indeed sound like the real thing. The pickup transducers are mounted on a piece of resin-impregnated board, and surmounted by a holly-wood bridge. Holly is a very hard wood; woodsmen in England use it to make edge tools for cleaving green willow rods.

The amplifier is a little overdriven by the E string (it's a 'clean' guitar practice amp of a nominal one watt output), but I needed the level to record clearly.

@ELCB -Thanks for the kind words, Emily. It sounds good for sure, but I have much work to do before I have a solid groove and the only way to do that is practice.

I'll leave it natural. I like the look of pine, and the light coating of spray varnish I've given it will protect it from me and my coconut oil (I use that to lube the strings). 

 

Well, that's it for this summer project. Previous projects have been a chambered electric guitar, and the solid violin which some of the Fiddlerman family have become acquainted with. I'll start dreaming up the 2021 project!
