Hi All.

Advice needed.
I ordered and received a replacement secondary (CNScope) however we got the measurement wrong.
I needed 96mm measured the long way, but the mirror I have is 96mm the short way, in other words too big.

So can I cut it down?
I have a diamond water cooled glass grinder used for stained glass.
It might be a bit slow, but worth a try, I guess.

Thoughts?
