Gage blocks on the cheap...

Me? mine are in the wooden case in a drawer. Dry. The humidity in this place rarely rises above 16% and they've never developed any spots, for lack of a better word). Mine are also way older than 3 years. I've had them for probably 2 years, maybe longer, and they were probably old then. When I checked them they were within 0.001", my mic doesn't go below that and neither do my eyes! If I need to machine something closer than 0.001", I have a surface grinder for that, and still I doubt I'd get anything much closer than 0.001"!!

One thing I recall from the days when I worked making gages (grinding threads), is temperature control. All measurements were taken in a 68 degree F room (man that felt good in the summer!) and the blocks were handled as little as necessary to prevent the heat from the inspector's hands from changing the measurements.

So what was the temperature in the room when you guys made your measurements?
