Thank you jcphillips for the nice comment and you are very welcome. At the bottom of the DF I used PVC plumbing that is used to connect Toilets in some way, I cannot remember the name of it but you can get it a Lowes at the toilet section. You can look at the picture of my DF and get an idea what you will be buying, remember to test to see if your PVC pipe fits before buying. This is then attached to a circular piece of wood that came off a plant stand I had laying around. You can also use a square piece of wood like the ones on the other DF. I have also added wheels at the bottom. Good luck on your project and let me know how it goes.
