More about the Bass

This was supposed to be something on parts sources, so I will say that I got the tuners and pickup parts from guitarpartsusa, whom I recommend. I didn't want to deal with an ebay dealer (I am over 50, after all, and I couldn't figure out how to do it), and guitarpartsusa was a good alternative. They answer stupid questions quickly, take your money, and ship the parts right away. What else could one want? I would've got the 24" "Martin-style" aluminum-channel trussrod from there as well, but they didn't have it in stock. So that came from StewMac.. I got a preamp kit from Jameco, but it's not quite right for the application (it specs max. 0.04v input). So I'll cook up a simple op-amp preamp from a plan in the book Electronics Projects for Guitarists.
    I started thinking about how the bass will fit in a case or gigbag, and that took me back to the drawing board for how the tuners are set up. It would not be good to have the tuning keys sticking up above everything else like they were in my earlier design. When I pulled out my drawings on the computer, I realized that I had the measurements all wrong, that the tuners are a bunch bigger in life than in my pretty pictures. So I had to abandon mounting them sideways, classical-guitar-wise. I was having a nasty time trying to visualize how everything could fit together, so I cooked it up in google sketchup, which is a lot of work but worth it. Below are size-reduced versions of the flat pix I've generated from the sketchup model.

the bottom ends of the body wings

They are not mirror images because I conformed the outer curves to the body wings as I had 'em in the earlier drawings of the whole bass.

The third picture gives some idea of the angle needed to have everything work right. One advantage of 3d modeling for the mathematically inept is that it allows one to find angles that work by just building the dern thing onscreen till it works. Ignore the blue box at the right of the first picture.
