Thank you Bob, and thank you too, Ken! Obsessing over detail and the potential for burning out is always a very real concern, of course. But I'm enjoying documenting my progress here on this thread, which has been very motivational. On the old WWIMML it really wasn't possible to share your day-to-day work, and without the kind of feedback one gets here my projects tended to stall and languish. I take the view that each major component should be a model (or sub-project) in itself; the Levasseur prop, for example, has been through ten incarnations so far, each noticeably more accurate than the last, and I'm still not done with it. But doing the research, and striving for that kind of accuracy is half the fun for me!
