CJ Your project to introduce the magic of pinhole to your class (in the absence of a conventional darkroom) is commendable. As someone who has attempted to do it the 'hard way' and learned from the experience I would recommend separating the activities of (a) loading the camera from (b) processing the images in the dark box as chemical splash/residue does not work well with handling unexposed photo-paper. You would only need to acquire a used (colour) processing drum designed for daylight processing. So the sequence would be: load camera >expose >unload camera & transfer exposed paper to drum for room light processing. Are you aware of the elegant solutions to the inherent challenges of daylight printing developed by Jim Kosinski (Starlight Cameras) ? http://www.paintcancamera.com/pages/524842/index.htm
