This is a rotating /revolving bin composter also known as a batch composter.

Warning: Woodworking is inherently dangerous. You are using sharp tools some of them spinning at large RPM's. You need to be wearing eye protection at all times, hearing protection as needed and because you are going to be working on some very small pieces you must use a push stick. Niether I or Instructables bear any responsibility if you do something stupid, lose focus, act carelessly, or recklessly. Also the saw dust from pressure treated lumber may cause skin irritation and depending on your source of barrel the contents may be dangerous as well.

I strongly suggest that you only use food safe containers.

Step 1: Obtain Supplies

You will need the following items

1) Foods safe plastic barrel

2) Hinges. I used stockade hinges you may want to use a piano hinge. It is your choice. I was not willing to drill that many holes or use that many screws, washers and nuts.

3) 2 Barrel latches. Yes you will need two.

4) 1/4 -20 screws and nuts. I used about 100 to build two of these.

5) Washers- to match the screws you chose.

6) Lock washers- to match the screws you chose.

7) About 18" of sheet metal.

8) 2 2x4's 8 ft long.

9) 1 1x6 8 ft long.

10) Two handles with screws.

11) Approximately 4ft- 5 ft of 2 1/2 inch PVC pipe

12) Outdoor grade wood screws about 20 -30 I went with about 20 that were 2 1/2 inches and about 4 that were 3 inches.

13) Masking tape

Thanks for the instructions. Made it with slight modifications.
<p>Vewry nice</p>
Great instructable! I would love an update when you figure out a guesstimate of time for the material to break down and any other observations.
<p>Depending on what you put in it and the moisture composition you can get good composot in as littlke as 4 weeks</p>
<p>Hey verga, I purchased a rotating composter but it was poor quality, the weight of it buckled the plastic legs so I built a frame for it similar to what you did with the your drum. I should have started with the drum like you did. The other thing I did was plumb my garberator directly to the center pipe of the rotating composter and then cut a drainage slot inside the composter. Now I'm in my kitchen, the garburator materials and water (I have a three bay sink, small middle bay is for compost / garburator material only) go straight to the compost pile. With some worms inside as well it all works like a charm. If you can get away with the plumbing mod I would recommend trying it. </p>
<p>thank you I will use some of your design with some mods. </p>
<p>Hey be sure to post a picture and describe the modifications you make,. I would love to see it when you are done. You might consider taking pictures during your build and getting your own Ible out of it. That is what happened with my first ible. I built a boat and some one made some changes and got a great ible out of it.</p>
I was wondering what are the advantages in this revolving composter over a std one that looks like a standing barrel? I can think of several disadvantages.
The first is aeration, you are putting more air in so you will get better decomposition.<br>The second is speed, More air more microbes, faster turnaround on your &quot;dirt&quot;<br>Third is ease of use I don't have to take a shovel out tot he compost pile and turn it over. after a while most compost piles get pretty big. This is done in small batches. I give the bin a couple of rotations and the fins break it up for me.
<p>Using a darker coloured barrel will result in higher temperatures inside the barrel (naturally), so that can make composting go faster. This is of course depending on where you live and what time of year it is - some places are in themselves already too hot for this to be an advantage.</p>
<p>If it's in an out-of-the-way area, you can attach blades (the fan / propeller kind, not the knife kind) and you won't even have to turn it by hand.</p>
