If you want a curve, you make multiple small bends close together, so it gives an even sweep, so it’s nice and round. But you can’t make a sharp bend on a thick piece of titanium, because it’ll break. You put the piece of metal in there and the machine presses down on it, puts a bend in it along a straight line, like folding a piece of paper. The curve lets it fit over the edge of the foam. It goes on top of the flotation foam and has long bolts go through it and the foam to keep the foam on. I think there was one on either side of the sub, port and starboard. It’s like a weird-looking triangle, six or seven feet long and probably four or five feet wide. I’m bending a radius on that titanium part. Here, fabricator Paul Keith talks about how he created a smooth curve in a piece of titanium. In the end, the iconic sub was redesigned and rebuilt, piece by piece, by a one-of-a-kind team of engineers, technicians, and pilots at WHOI. science community’s only human-occupied submersible dedicated to deep-sea research, underwent a thorough overhaul and upgrade to greatly enhance its capabilities. ![]() From the beginning of 2011 to May 2013, Alvin, the U.S. ![]()
