BobbyG66,
I made my spinner using parts that I got at Ace Hardware. I used a 6" long 1/4" carriage bolt. It was cheaper than the threaded rod.
All of the hard are in these pictures came from Ace hardware.
1 6"long 1/4" carriage bolt (head cut off).
2 flanged ball bearings.
2 bronze sleeve bearings (to reduce the 3/8" hole in the ball bearings to 1/4")
4 large fender washers for fly wheel
4 nuts to fit carriage bolt
1 Black knob with set screw.
I might have to look into the Bunny Knob, I like how quirky it is!
