In this video I show how I made a compost tumbler for free using recycled materials, including a metal 55 gallon drum. What is your experience with using compost tumblers? Are they worth the trouble? [youtube]watch?v=s8v7yjEASds[/youtube]
This is the tumbler my hubby made for me in 2007, I love it and have gotten several gallons of beautiful compost from it..... http://www.gardenstew.com/about8112.html
I stole Toni's design and have one also which works pretty good. Only thing I'd have done different would be to add something to help break up the stuff when you roll the barrel.
