I came up with this idea because I don't have a mill...yet! I actually chose the engine to build after I designed the flywheels (engine not done yet). The basic demensions are .495 thick, 2.325 dia. 0.20 rim, and a 0.725 hub, the spokes are 0.150. I started with a puck and removed all but 0.075 which leaves the rim and hub as one piece.
I then used the three jaw chuck to mark where the spokes will go and the drilled and taped on a drill press.
The spokes are turned from 12-32 brass screws and a little thread lock is used.
Then the left-over 0.075 is removed from the back and a little detail added to the hub, done! and wow do they spin true! I am sure using pressed in spokes would work just as well.
