aw, Clayy, I didn't ignore you. I've been busy on a bathroom remodel and just hadn't responded to everything. Anyways, I'm a REVERSE snowbird... I live in Arizona and go to Indiana for the summer. I'm leaving April 15 so won't be able to take advantage of your knowledge or your YIG offer. I have been watching your occasional posts with the mystery (airplane?) water-cooled cylinder and appreciate your expertise. Maybe we'll get together in the fall and compare projects. Sorry for the snub...
