Notes:
It is important that the bass is ergonomical and easy to get around. The ribs around the shoulders should not be too wide, maximum 20cm not including the edges. 21.5 with top and back. It would be advantageous to have the back break set quite low, at about the widest point of the upper bouts. the widest part of the upper bout. The bass will mostly be played seated, almost like a cello.

The fingerboard should not be too wide, about 40mm at the nut with string spacing of about 9.5mm. String spacing at the bridge should be 26mm centre to centre. The fingerboard should preferably be quite long and able to play the notes G, G# and even F.

Preferred string heights:                             5                        5.78                          6.5                    7.25
Overstand, provisionally 48mm including the fingerboard.

Interesting discovery during fingerboard research

Image
 I'm doing a comparison of 4 different fingerboards with 3 different playing set-ups. It will be like an article and it is not finished yet. But I did discover something interesting.  When setting up a new bridge, I've noticed that even when everything is perfectly centred, When you look from the front, it's like the strings are more to the bass side. I assumed that this is because of the thickness of the strings, and I normally compensate for it by marking the string centres on the bridge slightly more to the treble side.  However, there is another reason, and this is because of the way the strings get progressively further from the fingerboard, while staying the same distance apart. It's like they are unfurling and that makes them stretch out towards the bass side as they "unfurl". It's kind of obvious when you think about it. I just hadn't thought about it in that way before.

Shaping corner blocks - 2 May

Image
 It was satisfyingly simple to clamp on the blocks onto the mould and mark them with the stencil. Everything fits so nicely together. The spruce for the blocks is straight and fine and shaping them was fast and easy. I will later attach them with masking tape and super glue. The corner blocks are only shaped on the inside so the delicate wood doesn't break when fitting the C bout ribs
