I've been making chassis out of a few feet of board and $6 of 1/8 aluminum plates for a bit now.
Here's cutting the box/apron:

And here's cutting top plates:

The only power tool required is a drill.
Couple of the amps:
Finish is Danish Oil on both of those. The above method is a little time consuming (miter cuts, gluing, finishing) but it costs maybe $20 a chassis total and they come out looking nice.
I just got a power miter saw and I'm planning on trying a more precise inset plate for the next batch of amps.
What wood is that first amp? It is beautiful.
You got it, brother! Sculpture is lacking in this hobby but it doesn't have to be that way. These things can be 3 dimensional. They don't have to be all boxes, neat and uniform, plain, and flat sided. I'm worling on an Art Deco chassis, on paper at the moment. I had one idea of using copper tubing construction with 5 or 6 stacked squares for the perimeter. Great job!
You bet. It can be a piece of art. Here is my TT and phono stage.

Yep! Is your phono stage, "amoeba," made from some Corian countertop?You've really worked "natural" shaping into those pieces. Nice. How do you find the precise position for a tonearm pivot point? Copy the original TT dimensions, I'd guess, using a square through the platter spindle.
The pre is made from a piece of marble I carved and polished. I had to drill 64 holes in it. I used a calculator from the vinyl engine website to get the geometry for the tone arm which is an old Black Widow gimble with a carbon fiber wand and the head shell is made from a aluminum bolt, all totally 12" length.
