Made it. My fiend has a welder. I went to a local iron works, got a sheet of metal about 2 feet square. They bent up the front part for me. We welded a pipe (any size less than 2 inch diam. will do) to the center, for weight plates. We added two small strips of angle iron to the upper surface of the base-plate to allow you to get your fingers under the weight plates when (un)loading. We drilled a hole in each corner of the angled base-plate to attach chains. Finally, I went to Lowes for chains and clips. Being as I'm a wimp, I also bought some PVC tubing to go around the chain to stop it cutting into me when I'm pulling heavy weights.
It's not pretty, but strangely, that doesn't seem to affect how hard it is to pull.
I'll attach a picture. Hopefully, the size is small enough for it to come through.
If you want better shots - pm me with an email address and I'll send a few more.
