Sharkfin. Attempt on an ergonomic bass

Postby Beate Ritzert » Wed Apr 04, 2018 8:00 pm

Well, this will not be a full build thread. I am going to show one or the other stages of the build process of that bass.

The shape ... is based on my ergonomic bariton guitar:

The fretboard is my first attempt to do a multiscale fretboard and the 2nd fretboard i make myself. On one of the old NOS necks i recently had a question on.

Testing the contour:

and glueing the top:

The body will be made of basswood. It will be unusually thick for a semi solid bass, but intensely chambered.

Progress will be slow, mainly because i am working on two more basses and other DIY stuff.
There are still many undecided things: the headstock shape, the vertical profile of the upper horn, the layout of the chambering.

Love it! (Although, I admit I don't know what is ergonomic about it)

Ergonomics - mainly he position on the leg. The short scale. The slightly smaller - gibsonesque - string spacing. The hopefully anatomically well fitting sculpturing of the back. And the multiscale fretboard - in this specific setting with neutral position at fret 5. I am also thinking about bringing the upper horn back to enforce a playing position which will allow me to see the neck from the back and therefore discourage me from staring permanently on my fingers (a feature i like on my archtop guitars).

Yes.

And actually a necessity as my hands often hurt from the load imposed during work.

And now fretted. Third time i ever did it. Unfortunately i had to glue about 2/3 of the frets because the slots were a tiny little bit too wide. I used fish glue. And NC glue for the saddle.

Some intermediate stage - need to work around a mistake when i tried to cut along a plane and had only the round contour of the body to mark that. Well, i need to accept a step in the line between top and body :-(

Is there any trick to avoid that? (I drew the line round the roughly rounded body with just a ruler, an i did not expect that that would be off "more than a little bit".

After filling that gap beneath the right plate and a bit of planing:

Maybe it looks trivial to many here, but it is the 2nd time i tried to bend wood, and i must admit that i am a bit proud of my success - i let it cool and dry forced into its final shape.

Especially regarding my improvised equipment and the comparatively large thickness of the wood.

35 years ago i bent a set of sides for my archtop guitar this way.

Looking good Beate!
One of the things I admire about some of the builders here, you included, is the inventive way some things get done.
I need your help. I can't possibly make all the mistakes myself!

Thanks.

Here a full impression how the top will probably look.
I plan two slim pickups in order to leave as much of the wood visible as possible.
