I made a pair of these back when I lived on a little postage stamp of land in the suburbs. They worked great there so I am showing the remains of one today. The frames are made out of 10 foot long lengths of half inch diameter EMT (Electrical Metallic Tubing) that you can get at any home center. I bent them up using an EMT bender, then MIG welded the butt ends together. The chicken wire is tied on with tie wire.
So bend your frames, weld them up, roll out your chicken wire on the ground, toss frames onto it, wire chicken wire to frames, and enjoy!
The last picture in my series is my new mulch setup. Which I like to call throw it into my woods. This is just the beginning of leaf season here. By the time I'm done that pile will get about 20 feet tall!
