@ArrowJ, here is a link to the plans I used: http://www.jurai.net/~winter/tumbler/tumbler.html Honestly, its pretty simple to build I really only used the pictures.
The bowls that I used contribute to the unit having a clean look they were sourced from Walmart in a 4 pack (the 2 smaller ones went to the kitchen).
I put the whole thing together in one afternoon(maybe 3 hours).
If you have any specific questions feel free to PM me.
