    Yes and of course "Durston" is the best.(although some may say
that I am biased). Let me know if you need more Sara

Hi Sarah,

Our Durston D2/120 rollers are somewhat worn in the centre and
rolled out sheet is over-thinned and buckled at the edges. What do
you recommend we do about that? As I’m in New Zealand I expect I’ll
be taking the rollers down to a local engineers for grinding down and
resurfacing.

  1. How do you recommend we instruct the engineer?

  2. How deep is the hardening on your rollers? Will we need to get
    the engineer to harden the newly ground surface?

Brian - I had the same thing done in the US; took the rolls to a
machinist, and had him run them down on a lathe (not ground on a
grinder!). Make certain to have them turned to the exact same
diameter, otherwise you will get differential stretching of the
metal when you roll out sheet. I didn’t have the metal re-hardened,
as they didn’t cut away the entire hardened layer. The mill was
manufactured almost 100 years ago; it was the first time it had been
turned down.
