Cut two 6-foot 2-by-4s into equal halves using a saw.
Put the four sections of wood on a work surface. Create a square with the wood by arranging them so they form a frame.
Screw twot 2.5-inch screws into every corner of the square.
Put a 3-by-3-foot piece of plywood on top of the square. Attach the plywood to the square with 1.5-inch wood screws. Use two screws for each edge.
Place the diesel engine on top of the square frame. Drill four holes into each corner of the wood, this will be to fasten the engine. Use 1.5-inch bolts and secure with nuts and washers.
Fix a pulley to the diesel engine by using an Allen wrench. Fix another pulley to a permanent magnet motor. Put the motor on the wood frame in line with the pulleys.
Fix a fan belt to the pulleys so the electric motor spins when the diesel engine is turned on.
Pull the motor back so the fan belt stretches and is pulled tightly between the motor and the diesel engine. Use a pencil or marker to indicate where the motor stops. Drill holes in the marked spots.
Fix the motor to the wood using four bolts and nuts and washers. Use a wrench to secure the nuts and washers.
Disconnect the cables that came with the electric motor. Do this so they won't come into contact with each other when the generator is on.
Turn the engine on. The diesel engine should cause the electric motor shaft to rotate as driven by the fan belt.
