There is a guy in Tulsa who is building a boat (svseeker.com). To say this guy is a Maker is like saying Michael Phelps can dog paddle. The boat is 70 feet long, an all steel, welded, junk rigged motor sailor. For example, he designed the propeller in 3d, machined the blades on his (home built) cnc router, and cast them from bronze in his yard. Go look at his site. It is the ship that the Internet built.
He is throwing an open house this Saturday from 10am to 2pm. I plan on riding up there just to see it and meet him. Visits at other times are by appointment only.
Check out his site and you might want to go take a look.
