What is the best material to use for a baseboard for an enlarger? Should I just get a piece of 3/4" plywood, cut it to the size that I want, and glue some Formica to it or is there something ready-made that I can use?
Consider not using a baseboard at all. You get the most rigidity and least vibration with a wall mounted solution. Enlarger and counter top are best to be separated.
