you can take yard clipping ,leaves and kitchen scraps. any organic material will work ,just never put meat in a compost bin. when its done cooking you have nutrient rich soil that you can use for all kinds of gardening applications
Step 1: Materials
1 galvinized chain link fence post
4 3.5inch 1/4 bolts with washers and nuts
6 or 8 6" 60d nails
one 55 gal barrel (must be food grade)
one piano hinge
one box of 10-32 3/4" nuts and bolts ( make sure they fit your hinges and latches)
paint if you want . I use barn paint from tractor supply co . its cheap and it doesn't require primer!
now I bought most of my materials but you can use what ever you have on hand also. the whole project only cost me 50 dollars so its not that expensive any way
Step 2: Assembly
take 2 2x4s measure and make a mark half way down both of them . then center them and bolt ( you can use nails but bolts work better) them together.
repeat for other side.
you should have two giant X's
it doesn't matter which way they go,so pick one side as the bottom measure up 3 inches from each foot for the bottom braces.
now attach your other 2 boards with nails or screw them together.
your frame is now done and you can start to work on the barrel.
you can cut your bottom braces a few inches longer than the barrel for a better fit but you don't have to .
