Step 2Make A Magnetic Flywheel
The flywheel can be made of 1/2 inch polycarbonate plate, or two pieces of 1/4 inch plate glued together. It is about 5 inches in diameter, and has 6 equidistant magnets placed in it by drilling 6 of 1/2 inch holes in the poly. The magnets should fit tightly.
Use a drop of Crazy glue to hold the magnets in place once they are inserted into the flywheel.
The centre of the flywheel must be same as the shaft size of the blower motor. In my case a 1/4 inch centre hole worked well. Back up the shaft with a washer before mounting the flywheel, and make sure the shaft nut doesn't back off by using Loctite on it.
