This fall I plan on making one of these. I was thinking about adding a threaded end to it, so you could cap the end and fill it with bleach water to clean sterilize. Or could you just stick a rubber stopper in the end and fill it with water?
Assuming I could clean and sterilize it, I was also going to use it to grind table scraps for compost.
I'll have to find pics to post, but I took a plastic wash basin and poked a hole in the bottom as the base for my press. It worked real well this past fall.
