A bit of progress:
I'm currently negotiating with FakeSnake, the making of Radius. His dad's been working in a machine shop for 7 years. He's got access to CNC and EDM, but I think we'll go with CNC.
I received the last of the parts from McMaster. One last order for clear polycarbonate glue, the endmills, and I'll have everything.
Utabintarbo gets a block too, for his tremendous contribution! Thanks Bob!
