Hello Engine Lovers: When the fish are not biting and you have
nothing to do, why not retire to your work shop and build a radial
engine?

I started this motor about one year ago and after working on it
between other jobs, I have finally completed it.

It is a 5-cylinder radial and-yes, you guessed right-I used 5
model 72D Maytag cylinders. The case is aluminum, the crankshaft I
made of steel, the connecting rods of brass. I am using one buzz
coil to fire the plugs with a homemade distributor.

There is neither vacuum or pressure in the case so I am using
fuel injection to the case.

The cylinders are spaced 72 degrees apart and will fire 5 times
per revolution. Naturally it will use 5 times more fuel, but it
will have 5 times more torque.

The motor is 14′ in diameter and the case is 4′
wide.
