Forgive me, but I am confused here.
When I talk about a hardwood machine base, I am talking about a large heavy mobile trolley. My CNC machine sits on top of that, supported at the correct key points. Now, if the wood in the trolley moves, or grows by 10 mm - so what? It's just a table.
Maybe what I mean by 'a machine base' and what others mean by that are two different things? To be sure, I would NOT use wood in the construction of a CNC - absolutely NOT.

Kills carbide tools however, and all screw holes need to be piloted and countersunk. Looks beautiful with teak oil...
Oh yes - definitely to both.
