Thanks, Dorn, for posting http://farmhack.net/node/383
I'd been feeling a little frustrated since I posted saying: "I want to put out the call for anyone to let me know about practical (tried and proved-out) home-built equipment or set-ups & devices, DIY projects, etc that can be of value to homesteaders, market gardeners, and small farms. I have a Pinterest board. This is something I'm experimenting with, using it to inform people in need of technical info." (That was in my post at: http://farmhack.net/forums/tell-me-about-web-pages-about-equip-projects )
I keep telling people about the FarmHack site, and some will check it out. But I feel also that getting the word out through other sites is needed.
No one had actually responded to the call I put out, but your post and the Rodale cover-crop crimper is the right sort of thing.
