T bought this air compressor at the I Hartford, Michigan flea
market. It has a 3′ bore and a 5′ stroke. It had one main
bearing and open gear reduction driven by an 8′ flat
pulley.

The only ID is cast on the side, and it says ‘size one.’
I made the cart first from scrap steel and flea market wheels. I
made the crankshaft longer and made a bracket and second outboard
main bearing. I used a 45 pound flywheel that I bought at the
Hoosier Flywheeler’s Swap Meet.

Because of the headless design, I made a new connecting rod
1′ shorter, added a new wrist pin and bearing, a crankpin and
bearing. I shortened the stroke 1′ to a four inch stroke. That
brought the piston up 1 inches from the bottom. I made a brass
carb, gas tank and governor. I used Volkswagen gears for the
sideshaft.

There is no intake valve visible. It had a short, flat, seat
valve inside of a brass fitting. I changed it to an angle seat. I
made a new exhaust valve and brass fitting for the muffler. The
pulley is from an emergency brake drum off a Dodge car.

The engine starts and runs nice at about 200 RPM. It fires about
12 times a minute. I hope to show it a lot at the 1993 shows.
