Gear Art Parts

Drawn in (inches), this is a bunch of gears and parts that I used in a
moving gear art piece I made for my son. Gears are loose fitting.
Includes an arcamedes screw with pinion gears, a piston and cylinder
and connecting rod and an air tank with gauge. I used a 12 volt, 10
RPM geared motor to run it. Some holes are for shoulder screws
and some are for bearings. I mounted everything on 1/4" acrylic.
I used "Gunmetal" Metalizer paint with smudges of "Rust" paint to
make parts look
