Please see my channel if you are interested in making these blades. This is my second wind generator made from a treadmill motor this time geared up 3.6:1. Many of the parts were recycled from the same exercise machine with the exception of 3" exhaust clamps, angle iron, nylon reinforced vacuum belt and some hardware and other incidentals. The spindle assembly fits the standard mounting bracket of the motor and is both adjustable (belt tension) and bearing supported. I de-toothed a saw blade for the hub and drilled it out with a precision collet index. The other parts were either bored out or turned down with a tool room lathe. I took the motor all apart and it looked hardly used (most are), and cleaned up the commutator for good measure anyway. The frame itself is mig welded steel. In the video you can see amps first then volts, around 4.5 and 22 respectively but the multimeter was acting up a little so not sure about accuracy. The Subaru headlight bulb is running one filament. Blades are thin gauge steel and almost 60" diameter and will start up the machine even when motor is shorted with very little wind. Will probably go with a deeper gear ratio and thinner tipped blades on the next one. Thanks for looking
