I have a couple of questions that have been kicking around lately.
First, I remember reading somewhere about a North Star Slab Roller mod
where the height adjustment knobs are replaced with a two gear and
chain setup to raise and lower evenly and quickly and if anybody knows
the reference text I would love it. Two, our Cress analog pyrometers
have gone well past their shelf date and we are looking at possibly
the digital units as replacements. Any comments on accuracy and use
would be appreciated.
