Oh, yes, that's very cool. I have the parts of three smaller enlargers I can cannibalize for this, if I decide to pursue it. I favor a horizontal approach, though. How hard to make a vacuum easel to hold the paper, do you suppose?

Years ago I made an 11x14 vacuum paper easel by drilling small holes in Masonite on an 1/2 inch grid. Another sheet of masonite for the base and strips of wood for sides and internal bracing completed it. A piece of PVC tuning connected to a vacuum cleaner hose provided enough suction. Others say that pegboard works, and saves some labor.

I picked up an adjustable vacuum paper easel (5x7 thru 11x14) on eBay some indeterminate time ago. It has a big hose fitting for a vacuum cleaner also, and slits instead of holes.

There is a posting on apug.org for a vacuum filmholder using a battery-operated fish tank pump with something reversed internally (explained in the posting). It was surprisingly simple.
