Those are all definitely good suggestions, but I really want to avoid using heat on the frame, because I don't want to mess up what's left of the original paint. The paint's what makes this frame special, as it proves that this frame was once a Black Phantom. The frame itself is a little too far gone for a full-blown restoration, at least in my opinion, but I think it's good enough to build into a rideable state. I just don't want to scorch the paint too bad. There's not much left to scorch, but still!
