Yeah, i can explain how to form the leather, how to do the rivets, etc, just PM me if you have questions.

If you're serious about making your own frame, be sure to look at all the crazy things people have tried.
In particular, look at the Lepper saddles (in Netherlands) that have a hand brazed 531 frame. I've seen photos but i haven't seen one in person. I gather they aren't as robust as a saddle needs to be. At least one forum member has one.
Also be sure to Google Giorgio Siligardi, who made some very interesting (innovative!) saddles in the 80’s. They come up on ebay occasionally but unless they're woefully maldescribed or miscategorized, the prices are insane. Again, at least one forum member has (or had) one. Vonruden may have a comment to share.
Before you try making the frame, i would also suggest you look at as many different saddle designs as possible. Idéale had some interesting designs until some time in the sixties or seventies, after which all their racing saddles had the same design as Brooks. Brooks hasn't changed the design of the B17 series since 1950, at which time all they did was introduce a cheaper nose design.
So it's clearly a design that works.
