Howdy All,
I'm shopping for my first reference surface. My nature is to buy the best grade I can afford. I'd like to be able to do some fairly precise measurements, and have an old Heidenhain electronic gage setup that can resolve to 0.5 micron. The question I have for the experts is "how good is good enough" considering that my workshop is not climate controlled most of the year. I live in Georgia USA and I only climate control on the very hottest and coldest days, so the plate would occasionally be subject to some considerable temperature fluctuations. That considered, am I wasting my money on an "A" grade plate? I also realize there are many factors to consider beyond temperature stability...
Your opinions are appreciated!
