mabie you just want a standardLooking for a reasonably priced *and size) gauge block.
Let me know if you have one you are willing to pass on.
Your micrometers didn't come with standards?I would like something to check the accuracy of my mic's and calipers. I know there are different sizes to check different lengths,
A 3/4", 1", 1 1/2" or 2" x 1", 3/4" (or similar) block would be enough to put my mind at ease. I was thinking a rectangle block would provide a length, width and thickness measurement.
