I'm planning to add a surface plate to my shop. I'm curious about temperature effect on the plate. I'm in North Dakota, my shop is my unheated garage. Maybe I'm missing something, but what I've been reading understand as the temperature extremes that are in my shop will basically destroy the surface plate. Am I missing something? The shop I used to work in wasn't very well temperature controlled, and the surface plate there seemed to be fine, but then again, I didn't need to use it very often. Ideas? Recommendations?
