Thanks sopticals for your reply, much appreciated. Mirror making is obviously not a big thing in Australia. I think its time I moved on to the Ronchi Screen.
Did you make your Ronchi screen or order it. I notice the US publisher Willmann-Bell sells screens at various lines per inch. I read that 100 is a good starting point.
I Think I have the structure of the tester working OK, just looking for some confirmation that I have the basics sorted.
