Here is the problem. A HF mini-lathe costs around $400, Homier sells
them for $299, so IF one could use the mini-lathe for $300, most would
much rather add the tool than pay others that same $$ to get a
machined part. Besides, the lathe is so darn useful for so many other
things.

But, most of us do not have a clue how to indicate or center a ball
screw in such a machine.

The 7x10 as well as many 9x20 lathes have a 3/4" bore in the spindle,
so there is a limit to the size screw one could do on these machines
as well.
