Excellent! I am going to build one. I have most of the components it takes, one I am not sure of is the threaded rod with the bearing at the end of it? The one that holds the wood block in place while allowing it to spin. What is it and where can they be found? Thanks for posting such a cool vid!
chet I don't have specs . This is my first prototype and I just built it with no plans just what was in my head at the time and a bit of trial and error.
