Currently modifying the wood chipper to better handle cardboard. I might even look at building a small conveyor belt. One that can sit behind the chipper and make the pile as it is chipped. Could also be used when turning the pile into the next stall. I can also see a mesh barrel getting bolted onto the cement mixer as a trommel.

The more i look at composting the more I like the idea of building a large tumbler. Maybe out of two totes bolted together. I have a couple spare that each holds 380ltr.
But due to the amount of cardboard I get from the shop I will be building a few static piles. If i can get the bulk of the pile composted without turning then it would make an easier job to run a tiller over it. Drying out might be overcome with the air going into a sealed bucket of water. Then from there it could go under the pile. That would keep the air going in with a higher water content. Also may mean you could add molasses to the water to help feed the pile.

i've never had much luck with the tumbler drums. I think they fall a little short due to size. Always wanted to turn a rain water tank into one if i could make a frame up to turn it.
I might set up a couple of piles and see if there is a difference. I know i will still have to work the pile, but it would be nice to cut that down a bit. I have a spare air pump that will push a 100ltrs of air 3mtr under water per minute.

I don't get a lot of time to work a compost pile and to get enough compost for the garden I need to set up a few large piles. What i was going to try was adding air to the pile. Either by setting up an air pump on a timer or using an air compressor with a long pole. The idea was to push the pipe into the pile every 4 or 5 days and force air in. Has anyone tried a similar method?

I've been looking at building one for a while also.  I like the idea of pushing hot air under the house.  The heater would be in an outside BBQ area so it would heat 2 places at the same time.  I was going to use a funnel over the fire so i can set up a grain or wood pellet feed.
