The actual air pump is small, plastic, not very romantic or iconic so I carved up a hunk of cottonwood to make a stout nodule shaped housing for it. Here are a few photos of the process.
To start there was a good heft to the log with a limb jutting from it.
I kinda melt and flow when I’m carving cottonwood.
Initial shaping and some sanding
Veering and swaying, I grind, floating around the grain. I left the frayed, velvety surface not sanded fine. It came to resemble something; a body organ, a heart, but it will need extra valve structures, fins, ports and jets radiating hoses coated in gelatin waxes. In my mind I often see things that are organ shaped objects or shapes that conjure up lumps of muscular knotted vine, root twists, orb clots packed with goo, fungus heads that protrude like swelled bones under meat.
More shaping and sanding
I feel soothed when an angular form rests near a rounded shape, flowing tubing encircling all around. So I mounted the pump housing on a rectangular plate of wood.
Mounting pump housing to board
The pump housing later became depended from a cast aluminum part of a helicopter engine. I can run hoses and tubing between pump housing and engine part to plenum the air to different places.
Mounting pump to board-left side
Eventually the air will bubble through some liquids that will be in vials and bottles in various places on the station. Having left the wood surface crude I like how it contrasts with the precision machined objects I mounted to it later. It’s not quite finished. Once I have the basic elements added I’ll mount it to the station. From then on I’ll integrate other systems of tubing, controls, to it.
