[Lab] simple CNC multibuild

[Tom Burns]

Sorry everyone, the original link was here:

http://hackaday.com/2010/06/21/100-cnc-mill/

and via the comments there was this updated version:

http://makeyourbot.org/mantis9-1

That one has enough details to actually consider building it.  There's some
improvements I would want to do (especially replacing the epoxy with a clamp
as mentioned in the hackaday comments)
