This guy has a few different projects on his youtube site, but I found his (still to be completed) build of a 74' steel plate yacht particularly watchable. Videos range from welding, distortion, casting, machining, sandblasting, a bit of CNC and logistics of DIY one-person operation with heavy steel.
