Thanks, but really I just want Karl's phone number.

How big is your shop [number of employees?] One indication of a
potential problem is if you depend on "Karl." A "Karl" is the
employee with a good [or lucky] memory that knows which machines
running which tools at which feeds/speeds to use for any given
job. The problem is what do you do when "Karl" is run over by a
streetcar?

Contact me off list if you would like to discuss this further.
