You're right about answering your own questions if you look hard enough for the answer.
Being an old motorcycle mechanic, I've bent a lot of frames. It's very common practice to heat a section of a frame with a torch and modify it. I've also cut off sections of frames, bolted frame sections together and brazed or welded frame sections. On my first motorized bicycle build, I was putting a multi-sprocketed wheel in place of the original coaster brake wheel. I discovered that the rear fork had to be wider in order to accept the new wheel. I simply heated some key sections of the frame with a MAPP torch and applied the right pressure to widen the space between the members of the rear for. No problemo. The new wheel fit just fine. Of course, it's something I'd rather not have to do, but really, it ain't a big deal at all.
