Some people seem to be interested, so I'll continue. Though before I do, I think it would make more sense for me to quickly explain my general set-up.
My guitars are mostly made at home, at a workbench in my garden (which periodically requires me to duck out of the rain holding an armful of tools). I have the option, however, of periodically taking stuff up to my wife's work so we can do things that require big, expensive tools like table saws, CNCs or routers. My wife is a scenic carpenter who runs a professional set-building shop with just about every tool you could possibly want. She's also a much better woodworker than me, it's handy.
Anyway, back to the build. When I first started making guitars I bought a big ol' slab of ash, something like 2.4 m (8 ft) of the stuff, to make bodies with. I liked the way it looked, but it was very, very heavy and, by the time I came to start work on this bass, I'd already used most of it. I decided to use the remaining length of wood, cut into thin strips, to make a multi-piece body from contrasting woods (the other wood being sapele).
I was inspired to do this by a picture of a bass made by a now-mostly-forgotten British luthier called Peter Cook, which I came across in Melvyn Hiscock's Make Your Own Electric Guitar years ago. Weirdly, when looking though my old reference images I realized that a bunch of them came from this very forum. So, er, thanks @FlatEric for providing those. If you read this, I thought you might be interested to see my Peter-Cook-Axis-inspired electric mandolin, which I made around the same time.
The last section of ash board was cut down on the table saw in my wife's workshop, then I set to squaring it all up and levelling the sides with my trusty flea-market Record No. 7.
This is the bass body with all its pieces squared up. It's not been glued in this picture, but I had already drilled the holes laterally through the centreblock for alignment dowels.
I cut out the side pieces with a borrowed jigsaw, and did the remaining bits of the centreblock shaping by hand. I drilled those pilot holes for routing before I glued the body up, because my drill stand wouldn't reach when it was all joined together.
And here's my hi-tech set up for carving out control cavities. Note the 1980s Bosch drill stand that my wife found at the back of the cupboard at work.
I didn't take any pictures of the routing process, but here's the router template for the pickup routs and neck pocket. My wife was able to import my technical drawings to her workshop CNC, and I then brought the body up to the workshop to use the routers there. I should mention at this point that I really, really hate using routers. They scare the shit out of me.
And here's the finished product. Pickups and neck pocket routed, as well as a recess for the control cavity cover on the back. The string-through holes and the neck mounting holes were done with the workshop pillar drill. All the shaping and rounding had been done at home with rasps and spokeshaves.
