Milestone today. Up on all four wheels
The front axle was modeled in FUSION360 first because I wanted it to look scale.

The center part was made from brass stock so it was easy to braze it and shape it. The center pin in O-1 drill rod because I thought I would need to harden it, but its plenty stout as is. The axles were made in two pieces in case I wanted to shorten them up. They are a semi press fit into the center part, but green loctited also.
First the fishbelly on the center part in the mini lathe (6 degree angle, 7/16" diameter in middle)

Then I milled a small bit of 3/8 SQ brass for the eyelet. Ran a 1/4 mill on the bottom with two 1/8 ball end mill passes for the turnbuckles. Later on two short bits of 1/8 brass go here. Then center drilled 1/16" and a bit of wire filler jammed in to fixture it all in place while brazing.

a small 4-40 hex head bolt is holding the swivel in place and I made a 3/4 bronze bushing to keep the swivel inside the perch. It is attached using two 8-32 grub screws (not shown in this picture)

I think It looks pretty freaking good.
Hmmm perhaps the crankshaft hole needs to be relocated forward about 5/16"? Compare to the picture in the background? Rim of the Left Hand flywheel is about flush with the leading edge of the horn plate.
