This shouldn't discourage you. Take the drilling pattern for the mod transformer from Hammond's website and start working on the scrap chassis. Once you have the RF section and PSU sorted out, you just have to plug in the mod iron to finish the project.

I for my part haven't gotten any further either, but that is hardly unusual for my projects. Too many irons in the fire as we say here in Denmark.

I have about 20m of some very heavy gauge copper wire buried in the lawn under the antenna, plus 5 ground rods, maybe 1 meter each.

The grounding will be improved next summer. I just wanted some thoughts on the basic concept.
Any long piece of wire up as high as possible will do nicely for reception on 3,5MHz and thereabouts.

How about posting some photos of your dummy load and/or your newly acquired amateur radio license, please? I for one am not going to help you put your 'science project' on the air.

Best regards
