I think I may have figured out how the adapters are configured for the disk brakes, starting from the frame going to the wheel hub.
Starting with the rotor, then the first part of the adapter is a spacer that is like a cup (kind of like the band brake drum, just with the open end facing the hub, not the frame), and next would be the freewheel and adapter (the freewheel adapter fits through the adapter cup), and the adapter plate with the two "prongs", and lastly the hub and all bolted together with three bolt and the freewheel adapters keyed to the axle.
On one of the pictures from the gentleman in Ottawa, I saw the one of the unused holes that is in the adapter plate that sandwiches the drum to the hub, so I'm mostly guessing, but if I have figured it correctly the hub with the adapter plate and cup only makes contact with the freewheel (guessing it's a smaller gear than the one I have) at the bolts, so the cup will spin around the freewheel adapter without touching it. But if anyone has a different idea, I'd love to hear it.
My original idea to try to copy this was to put a thin spacer against the hub, then rotor, then adapter plate with the "prongs" and bolt it to the hub, then have a spacer adapter going from the frame to the caliper to put the caliper where the rotor is and use the current freewheel setup. Bonus to this idea would be easier to put a large rotor on it as the spacer adapter would have to be welded/machined, downside is the spacer would maybe have to be custom machine and cost a bit, also may put a lot of leverage on the frame in a hard braking situation and possibly damage or fail a few parts, but a strut rod from the spacer to farther forward on the frame and bolted to both might be enough strength to keep that from happening. Again any ideas will be welcome as I have nothing set in stone and I'm just enjoying the bike the way it is, I am really thinking about a Loadrunner 2 though, could be nice to get groceries with and not need a trailer, the Rhoades is just too big to park at a bike rack, but I may ride it past my local Walmart someday just to get looks, lol
