I just built this cheese press in about 20 minutes.
I used cull wood from DIY mega store, some metal braces, a garden gate hinge, and plain old wood screws. Total cost ~$12. I cut a notch to hold the weights on and marked distances for 1.5, 2, and 3 times the end weight for pressing. I also cut a few different length pressing bars for different sized cheeses. I'm gonna pick up some used exercise weights for both ends (needs a counterbalance, heh) but for now some water jugs will work.
