Wiring

Now that all the pieces are in place the wiring begins.

Under control

Here's the inside of the controller with the PWM and the lithium battery from the drill.

Mover and shaker

I've been using all sorts of different motors and power supplies over the year. But I had to find something that works and commit. I found a lithium ion powered 12v drill with two small battery packs. Here are the parts I salvaged from the drill. The motor went into the wooden barrel and the battery will fit into the old train transformer.

And here's the more powerful PWM that I bought to run it all.

Just painted

Here's the compressor piston that I'm calling a pre-charger. All the non brass parts painted. Ready for mounting.

And here's the splash shield painted. It's made of brass but my soldering work was so bad I felt it needed paint to fix it. I used brass toilet hinges to mount the shield to the platform.
