I need to know how to build a gas powered scooter...ive got the chain saw engine but i need to figure out where to get the base for the scooter and what its called..? Unless you have some real great mechanical, welding, and metal working skills, just buy a scooter. It will be cheaper.
Good Luck Take what you have to a machine shop and explain to them what you want to do, they can figure it out and make a base for the motor. It will need to be built accurately so it is the center of balance. # Get a scooter with hand brakes and inflatable tires. Scooters with hand brakes have the best stopping power. Inflatable tires allow for the vehicle to handle rougher terrain. Child scooters such as the "razor" are not suitable for this project, because they use hard rubber wheels with pre-pressed bearings. One may also build a scooter frame (requires welding).
# Prepare the chainsaw engine by removing the bar and chain from the machine. Leave the rest of the chainsaw intact. Leaving the motor in the chainsaw housing makes it easier to attach to the scooter鈥檚 deck.
Unscrew the chainsaw鈥檚 centrifugal clutch from the crank shaft. The power from the motor will be transmitted through sprockets and a bicycle chain. The obvious problem with this approach is that you will never be able to "idle" with the engine running and the scooter stationary, and you will have to lift the rear wheel off the ground to get it started. One may also keep the clutch, and use a chain that can fit to the sprocket on the clutch bell.
# Bolt the other sprocket to the rear axle of the scooter. This may be easier said than done--carefully select your scooter knowing that you may have to modify the rear wheel mount, and fix the sprocket onto the rear wheel.
# Place the motor on the rear of the scooter platform to ensure the sprockets are in-line.
# Drill holes through the platform and chainsaw motor housing so that they can be bolted together. Note that most modern chainsaw housings are made of plastic and you will need to be very strategic about where you are attaching bolts, and the size of washers you use (to keep them from just pulling through the plastic).
# Wrap the bike chain around the sprockets. Remove the necessary amount of links so that the chain is taut.
# Attach the hand accelerator to one of the handle bars.
Wire the hand accelerator to the 鈥榦n and off鈥?wires on the chainsaw motor. This allows the rider to control when the engine will power the scooter. |
