I went the easy route. I had all the materials and just created as I went. My neighbor cut, raked and baled a small field for me and would not accept anything for it. His wife did all the raking and it was 95 deg and she wore a big hat, so I decided to help her out. It was "her" tractor (an M50xx something). He baled with an M9540.
I did not drill any holes, only used what was already there, even for the rod used to brace the outer edge.
