Here is a quick note, In the heat of last night I probed my solid carbide probe tool and left it where it stopped and re-ran the same setup in the cool of this morning and only saw the offset change by .0005" ! What with expansion and contraction with the whole machine I would say that is very Good indeed, assuming of course that I am seeing a true representation of what is going on. I have had the opportunity to do the same thing to large vertical turning centers and see well into .016" change in the same circumstances. I bet that if I went out there and reran the probe it would go back to where it was before this mornings probe. This is getting very interesting ! I got something to do, so, later !
