A 4-1/2 HP Olds Hits the Shows - Finally
Something's wrong with this year's Fall Fair project; usually the paint is drying on its way to the fairgrounds. But this year, the 4-1/2 HP 1910-12 type A Olds engine I finished last fall too late for the fair is done. I replaced the valves with turned down truck valves and reamed the guides to fit. New rings were ordered from Paul's Garage listed in GEM. The rest of the engine just needed to be sandblasted and painted.
I got carried away with things for the cart after going through my parts shed. The front axle is off an old fork lift, the 90-degree pulley-drive is a cut-down rear-end (car unknown). The transmission with open shifter fork is from the teens or early twenties (car unknown). The rear drive is a cut-down Dodge using the emergency brake band as brakes controlled by an old brake peddle.
The completed project, engine running. Power take-off from the flywheel is clearly visible. An old pump handle does duty for clutch control, and a slider with an old motorcycle shock spring cushions the rider.
The wheels were made in England (use unknown). We rolled 1/4- by 6-inch flat bar around them and screwed on car tire facing. The steering box came from a car (car unknown) and a pump handle is used for clutch control. A friend who collects scrap wood built the battery box. Fenders are off a Sears riding lawn mower. The #79 iron seat is bolted to a machined aluminum slider from where I worked 25 years ago. I installed a motorcycle shock spring inside the cylinder for a softer ride. It just goes to show you, never throw anything away you may need in time.
In order to show people who do not understand how a hit-and-miss engine works, I decided to take the power off the flywheel to show them the engine will fire every time under load. I may have to change it as third gear is too much of a load for the engine. GEM is great - the pictures, projects and information gives inspiration to us all!
