I'm going to take my existing workbench apart and use it to prototype my CNC stand and new workbench.  This should be relatively straight forward, the old bench is similar in size to the new bench.  However ultimately I want to build this all out of sheet goods and build in drawers to it all.

Here is the CNC table, for now I'm going to make it have an open front and no shelf so I can roll my shop vac in under it.  I have this sized up large enough to support my future larger CNC machine.

Here is the workbench, you can see it is not very large.  However it should be large enough to do most of the work I can manage in this small space.

I spent some time modeling this up with different sized casters.  The 3" casters sick out quite a bit, the tang makes a diameter of 8.9 inches when rotating through its full path!  The 2" wheels I have ordered work better, they only make a diameter of 5.9" or a savings of 1.5" in either direction.  We will see how well they roll when they arrive.  I may end up using the larger swivels on the workbench and smaller ones on the drill press and CNC table.

I have my table partially stripped down, I need to finish this up and build it back up in its final form.  I don't think this will take too long, I have all the material to do this and I only need to strip it part way.  With this done I can focus on making the new utility carts for the saws using my existing workbench to build on.  Then as a last step I can rework these two benches into there final form.
