Now I have machined the one side of the buttom part:

and the table itself runs like a dream because of the small balls:

unfortunately I have to machine the top part again, so the balls will be covered:

Now I shall machine the sides and the inside of the housing from the buttom side - that's a job for my mill, I think.

I'll try to make room for a small stepper motor - but I'm not sure that a stepper that small will have power to drive the table - maybe it can if the table is free - but I want to use the stepper while machining an object on the table too.

Do you think the stepper from an old printer can do the job ?
