Thanks for the interest. The only vacuum is for the splicing table, there is only the one tensioner, and the hose running from the coating head in the photo is a drain from the waste collection tray.
I will enquire about emulsion recipes, but I would guess that at this stage he is brewing a pretty standard analog of the commercial products. The final product is ISO 100, by the way.
One thing I forgot to take some photos of is his emulsion preparation equipment and tools. His reaction chambers especially look impressive.

I can't quite work out where the web goes after the tensioner.

It's difficult to get a whole photo now, but I'll see what I can whip up. In this case, the web goes straight across to the rollers on the left. All the extra rollers are there to aid the threading of the machine, but aren't used when coating.
