Yes, actually, Jen and I noticed this... it began late into the Reg
Day run...
I doubt it's the rollers or the assembly that moves them, as the
squeak-squeak only happens as the rollers travel up.
After the LSC job is done, i'll spend sometime listening and looking.
Probably next week.

Indeed... we oiled everything in sight at the time, with the same result.
I guess my hope that some of the oil would settle into whatever crevice
was causing the problem was misplaced.
There is a card on the bulletin board above the stone, that oiling
dates are marked on. It's also useful to send e-mail, as the
difference in speed can be surprising, and surprises can lead to
accidents.
If anyone notices anything strange about either press, I like to be
told as soon as possible.
thanks!
