I am interested in making a compost bins that rotates in the manner of the compost tumbler or the mantis compost twin. Do anyone have plans(instructions) or ideas about this. I know a few years ago someone had exact plans on how to build one, but unfortunately, I can't findt that.

Also, I have a lot of pine tress on my property and I'm told they add a lot of acidity to the soil. Any recommendations on how to amend this frugually?

Thanks!!!!
