So I think lugged steel frames are great, but for the money it takes to get one custom made, I think one of these days I'll just have to build one.
I have the Paterek book. It has a lot of good info. Henry James seems like a good resource. It'll be 100 years before I actually get to that point, but if I could build something like the piece of art you've produced I would turn backflips.
Anyway, what geometry did you choose, and how did you go about deciding on that geometry? I've built car frames, and there are very specific reasons and justifications for building things in a certain way. There seems to be very little information on bicycle vehicle dynamics and the geometries seem to be chosen in a very touchy-feely way. I think that some of the motorcycle information would transfer, but I don't really know how much is applicable.
If you've build scores of frames, I'm sure you have your pet theories, but I'm very curious how you approach the problem.
