RE; cheap digital
I am in total agreement with that!
While I admit that it is prim and proper shop practice to check the zero of a caliper before using it we all follow that procedure,, right?? Ya right!
Well those cheapo digital calipers will put you back into good shop practice believe me as I found out after spending a hour making a part that was totally out of tolerance due to the fact the stupid cheapo caliper zeros wherever it happens to be set when turned on. I placed that fine POS in the vise and squished it. Normally a person would notice such but as I was taught I always close my calipers all the way and then open them just a bit before placing them in the tool box, I never store them closed all the way.
I have a set of digital Starretts that are fine calipers but my day to day usage is still dial type. Cheapos are good to have around as long as they are not the bottom of the barrel type if for no other reason to give to the borrowers.
