I'm helping "the kid" with a new venture. He's making about 50 M2
tripods. http://tinyurl.com/3d4gmef

I get to CNC machine a few (well several) parts and will keep five
tripods out of the deal. I just made the first prototype run
yesterday. I'll set up the CNC lathe for production over the next
couple days. Same thing with the CNC mill.

Anyway, this unit needs half a dozen odd ball springs. Is there a
better source than McMaster Carr out there?
