Louis,
There are home built rigs and then there is the real deal. Huge difference
in performance. You will never achieve a correct finish using a converted
grinder, because the balance and the shaft bearings are not up to the task.
That is why they cost what they do, even used. Remember to cover the ways
and carraige with rags before grinding. The swarf is very damaging. Also
..003" is a big cut and use a very slow spindle speed.

Was looking through a PDF of Advanced Machining Handbook from the 30s,
look in a retro way. It had an illustration of a toolpost grinder. Now it
makes sense.

But other than 1,000 and up, who has a serviceable model for less (less,
less) than that?
