For the price of a subtable built right, I can just buy a small machine.  
But isn't that a case of buying a machine to work on the other machine?  
But thats recursive as Bertho described.

That's a good idea if your mill can't reach the speeds needed. Of course 
it costs nothing to test just run a stl file through a slicer and remove 
all the M codes and see if it can keep up. Z is super slow so that's not 
a problem.

You might consider building a lightweight sub-table and just move that.

For the size of projects I have in mind, 5x10 inches would be sufficient. 
Belt covers for the timing belts moving my lathe. Build from the outside 
puts the flat face on the bed, and the hollow part facing up, I should 
be able to write that g-code myself.

I hadn't considered the ballistics of a 70 lb table. That may present 
uncontrollable build height problems in
