Mad lad/scientist out of 10. “Would like to know more.” I’ve always been very amazed by the power of ECM rigs. It’s amazing home technology that’s absolutely RIPE for experimentation with things like progressively faster twist rates in the same barrel. Machining that sort of stuff is difficult, but ECM you almost just set it and forget it. I’m also very interested in the EDM kit that is being worked on at the moment. I think the name is Rack Robotics, but I may be remembering that wrong. That will be awesome for DIY tinkering.
