CNC Build Part 0: The Base

I’m finally getting around to building a CNC router for the shop.  The first requirement for such a machine is a solid and stable foundation.  Due to limited shop space, I constructed the base on casters so I can move it around.  The ‘pod bay doors’ on one side provide access to a ventilated cabinet for the electronics.

The top surface is constructed as a 2 1/2″ thick torsion box with birch plywood skins for extra rigidity.

The other side will have 5 drawers for storage of end mills, collets, tools and supplies.

Next week we’ll begin constructing the rails.
