I've been toying with the idea of doing a frame 'rustoration' after watching monkeyshred's youtube video. His frame looks roughly as rusty as mine, so I'm suddenly hopeful that it's a rideable frame.

But.

I'm no expert. And I don't want to die (or pass the bike to someone whose life is shortened by it)

Does anyone know of a reliable way to tell whether the frame is structurally sound or not?

I look forward to the bike gods smiling on me - so far they've mostly rained on me
