Hi Bob,
This is not something that I would experiment or try right away. So far I am
only doing small gum, and hand coating works fine, but since we are talking
about it, I thought I would gather as much info. as I can. Who knows, maybe I
will try it some day.
And it seems like for trying, it doesn't take much. I have speed drill, so it
doesn't need any more equipment. But right now I don't have any clue of how it
is done at all. Does one pour the emulsion in the center and then let it spin?

Do you happen to remember how large was large. Since you mentioned about the
use in a blue print business, it must not be very small either.
