Cleaning Out The Closet

I upgraded the vertical column on the Sherline vertical mill a couple of years back.  The newer version works more smoothly than this because of gravity.  If you have need to move something fairly precisely (to .001") and repeatably (especially not against gravity), this is the right gadget.  I've offered it up on Cloudy Nights for people building their own telescope mirrors as a way to make a very precise Foucault tester.  If you have some possible need for something like this, let me know.  I offered it at $50 on Cloudy Nights, but I can be persuaded perhaps to let it go a bit cheaper.
