Very good! I have an unused 1/2 inch drive socket surplus to requirements that I can machine off for the job. I'm guessing it should be welded to the steel plate with a high tensile (low hydrogen) rod, or MIG welder. I could try it first by welding the offcut piece of the socket with a mild steel rod, then seeing if it will break easily.
Choosing this option over the spinner and cone drive means I don't have to wait weeks for mail order items to arrive.
