It is very practical to make contacts this way. I would suggest putting
a bulb (experiment with wattage size for practical exposure times) in a shaded fixture as high above the print area as possible (for evenness
of illumination). You can use a foot or hand switch. If you want to get
fancy, you can use a commercial timer or a "ticker" made from a Radio Shack piezo 2-ticks-per-second ticker (it has two larger value caps in it - parallel each to find which controls timing, and double its size
to get one second ticks). Use a black sheet under the photo paper
to prevent reflections from the table surface going back up through the photo paper. A sheet of spongy material under everything helps to keep
negatives in contact with the paper if you are using a plain sheet of
1/4" plate glass (cheap at the local glass shop - have it "edged" to
avoid cuts) for making contact prints.
Hope This Helps
