Sounds like a great plan to me. Keep us posted on how it works out. Glad you're getting back into it. I just switched to SFG this spring. I like it much better. Try starting a thread on the Soil and Compost site. Lots of activity there. Good luck.

Jefuchs, I made a compost tumbler out of a 55 gallon barrel years ago. Turned out to be waaay too small but you'll overcome that problem by having multiple cans.

Something that worked with the tumbling was to drill holes in the metal and install 4 inch bolts. I'm not sure if these would help you but I can see your material coming out unmixed - in one big "clump" is it were. You could put a bungee cord over the lid, lay the can on its side and roll it. As I say, I don't know if that would be of wonderful help.

The mass is smaller than what would be desirable for a compost bin. You may be able to help retain heat by "bunching" the cans close together and maybe by throwing some insulation around them.

You may want to try the cans in vermicomposting. Putting one or more cans inside each other with holes drilled in the bottoms might be something to think about. You'd need to make sure they don't get wedged tight together.

One thing, your FINISHED compost will be nicely protected in cans.
