https://www.flickr.com/photos/[email protected]/sets/72157624130679622/I think I am going to do this. And comments are welcome. I have some 5/8” nylon cutting board. I’ll take a block of that and put a shallow round depression into it and fasten it to the bottom of my container (a 44 gallon Brute food grade trash container). The nylon block will be my bearing. I am using all thread for the shaft. I will put an Acorn nut on the end of the all thread. The depression in the nylon will receive the round end of the Acorn nut. I’ll then add another layer of 5/8 nylon with a whole drilled all the way through. That will help keep the Acorn nut centered on the bottom block. That will be my bottom bearing. I’ll only be doing 4 or 5 medium supers so I think that might work.
