These videos of large ship construction amaze me, but I was really taken with the part where they have to curve thick steel for the hull (near...
This video caught my attention. I am thinking of all the "rotted frame" stories we get. This looks very handy. [MEDIA] Edit Another good one [MEDIA]
For the terminally bored, a bit of mental (mathematical) exercise. Over in the Flettner thread, we've been discussing the challenge of...
