You probably don't need to see DURING exposure... it's before you press
the button for the light -- you also want to be sure pressure is up before
you start exposing.
I don't visualize your vacuum easel, but on my nuarc it was important
otherwise, too. for instance, the full pressure was too much for many
papers-- indenting or embossing them, and/or making the neg stick to the
emulsion. I used the bleed valve to lower the pressure waaaay down (I
don't know what those things were planned for -- maybe woodburytype!) --
finding that the first figure on the dial was enough. (Don't remember what
that was.) But the valve tends to wander, and you just want to see what
the pressure is. I got another vacuum easel for the darkroom that came
without a bleed valve -- was a pain in the neck. I installed one (cost $35
& then I had to cut a hole in the tube, but what a relief !).
Anyway, my suggestion is, wait until you've used it a while to be sure you
don't need pressure gauge. How about cutting a hole in the drawer?
