I got an Etalon micrometer precision level off of ebay for 113.
I had to figure out how to recalibrate it...the know is a morse type
taper..baby taper that is. Not intuitive for me.
Had to cut, heat and reform extension spring. Got calibration knob
within 1 out of 100 divisions(good as I can get it)
It resolves .000024"/ft., it really does. I put a LOT of work into it.
The cross pin the spring hooks onto was missing and the wood case was
smahed by usps(NEVER have important stuff sent usps), but i gorilla
glued it together. The level is MINT. 25 hundred in enco and msc. Me
happy, me sell Storeitt master precision level. Its like holbing a
baby...she's shweet.

Ch**st almighty! Fart and the change in floor loading would make it move. Good

Heh! I got a Talyvel 3 on eBay about a year ago, and it is able to resolve
0.1 arc second, which works out to 5.8 microinches per foot. It is also
supposed to be able to hold a reference to absolute level of .2 arc second,
although I think mine isn't quite that good anymore. It was JUST the
thing to help in precision hand grinding a 6 foot lathe bed straight.
(It is hardened all the way through, no way to scrape it!)
