Hard to see much about it ... but there is the basic frame
I'll end up shortening the extension of the headset tube a bit.
The 20" front headset was slightly diagonal to the rear bicycle frame,
so I pushed a helper bar into the neck hole to tug with while I pushed
on the bottom of the forks ... and tweaked it into lining up.
Then I welded it down into place.
It's coming along.
More detail fotos tomorrow.
