Dwayne's is a much more massive engine, and is a lot more stable than mine
to begin with. I hadn't thought about the effect of fingers on the fans-
perhaps a belt drive with a rubber band would be a good idea. I wish I'd
taken the opportunity to see the insides of his- after working on this, I
have more appreciation for the technical difficulties.
Pictures, Dwayne, pictures! I seem to recall a lot of your newer creations
at the GATS show that aren't on your web site (or the club's).
