I don't build frames, but I have designed products, as an engineer. I think it's valuable to know as much as possible about how to build what you want to design, and what the engineering, scientific, and craft-based issues are. If UBI is a good source for that knowledge base, maybe you should go that way.

On the other hand, some distinguished builders, such as Doug Fattic here in Michigan, offer group frame-building classes at their own shops.

Either way, you'd be on top with technical knowledge, and you'd have to tools to proceed and learn framebuilding. I doubt either knowledge base is taught in design studios. We certainly didn't get it in engineering school.
