With all the talk about spoke flywheels going on I decided I would make mine today. It's a little bigger than the plans called for but I figured I needed the weight because I am using aluminum. I used Marv's flywheel program to get me started. I have to fess up though the 5 1/4" holes that are in near the Hub shouldn't be there....I didn't start at 36 degrees like the print out called for. I started at 0....DUH... At least it ended up between the webbing and I was able to duplicate the screw up with just drilling 4 more holes 72 degrees apart.)) First I milled out the narrow part of the flywheel Then I drilled all my holes using a 1/4" drill Then I milled the excess material between the holes Here's what I ended up with.
