Scale Model Running Challenger Flathead V8 By Ron Colonna
Bore: 1 in.
Stroke: 1 in.
Displacement: 100 cc
Max RPM: 6,000
This engine was built early in my gasoline engine building career. I received the castings and drawings as a Christmas gift from my wife. I had it running about five months later. This is the engine that creates the most interest at the shows. So much so that I've had to rebuild it twice because of wear. As designed, it had some major shortcomings. The conrods were bronze castings which promptly wore grooves in the crank. These were replaced with rods machined from 2024 aluminum. Pistons were remade and the engine fitted with rings made from the George Trimble method. Oil control rings are a necessity as the engine smokes badly without them. An electric start system was added and the engine now runs with the push of a button.
World smallest V12 engine
Apparently the builder's name is Yesus Wilder and he only used three
materials to build the engine. Stainless steel, aluminum, and bronze.
All credits to him.
Scale Running Model Harley Panhead Engine by Ron Colonna
Bore: 1 5/16 in.
Stroke: 1 1/2 in.
Two Cylinder Four Cycle
No Castings Used
This engine was scratch built to a scale of 2/5ths or 40% of full size. The
bottom end was taken from a drawing of a Knuckelhead engine that I puchased
on e-bay. The top end was patterned after photos taken from e-bay of Harley
parts for sale. I also bought a Harley repair manual that helped with the
oil system. The crankcase was split into three sections instead of the
usual two for ease of machining. The ignition is solid state and I use a GM
coil which fires the two plugs simultaneously. Timing is advanced and
retarded with the timer body. Two rotating magnets fire a Hall effect
device at the proper times as per full sized points. The engine is large
enough to produce that lovely V-twin sound.
