You will find complete instructions in these videos. Good luck.
I used pallets..screwed them together 3 in a U shape..no bottom or top, then add 2 more in an L shape to add another section and then a third section. This gives you 3 U shaped areas to flip the compost in varying levels of decomposition. Easy. Free. Does the job.
I saw a pretty cool idea using pallet wood: Maybe you want to give it a try https://www.youtube.com/watch?v=fW_DVNUt7ms
Hi Rosario - Here's a great 101-style article on getting started with composting and everything you ever need to know. Also how we DIY'ed building our compost bin. My Stepson built it for a Boy Scout merit badge. Hope this all helps and happy composting! Hugs, Holly
