Paul C said: "It is important to develop a "feel" for your micrometers and calipers when closing them against your specimen and closing them. Without this important control, you will not get consistent, dependable measurements. BTW, these instruments must be stored in their closed position to keep them clean and corrosion free." Paul, I was informed by several machinists that you should NEVER store your calipers or micrometers in the "closed" position. Due to the expansion and contraction of the metal the "frame" will warp, if you do. Of course you should wipe the micrometer or calipers with a very light oil to prevent any corrosion. Also, I'd advise that you store your mics & cals in the box they came in. This will keep the dust and abuse away, IMO. Joe Garrett, R.P.T.
