Lone inventor makes breakthrough in screw-thread design ... at least, he thinks so

Is it possible for a non-engineer working alone at home to discover a breakthrough in something as basic and well-studied as screw thread design. Almost certaintly not, but you never know.

That's the essence of my Telegraph column this week, concerning a New Hampshire man who says 3-D printing of a new geometry of screw threads demonstrates that he's no crank. As I note in the column, his presentation with the items is certainly impressive - but it's easy to impress a layman like me.

He's trying to crowd-fund money on RocketHub to create a software library of these "wave thread" designs that would be freely available.

Here's my column.
