[Lab] [ORE_bits] CNC machine

Model B works for me - or maybe even a smaller number of shareholders - it
seems more like a 'timeshare' to me. I would suggest a smaller number than
10 though if there is not a mutually agreed upon highly accessible
location. Or... have the ability to buy more than 1 share.  For me it
starts to get interesting at one week per month - as this would be about
enough time to work on the files/projects ahead of time as well as complete
the finishing work on cut projects.

I am still working on a DIY machine though.... I have steppers, T slot,
Ball screws, and a father who is a machinist.... I may need to pick some
folks brains in the coming months.
