Not counting planning, of course, or endless software stuff ;-)

The fork-rectangular tube joint cracked once, then I welded a 1/4" strap to it.
Just as well, as it was slightly out of alignment.

The old one-piece style. I cut off the arms and drilled and tapped the ends of
the center for 5/16-20 screws. Then I made a rectangular bracket around it that
the front frame is welded to; the screws go through it into the center bearing
shaft.
I welded the front dropouts last, as their final placement compensates for
slight asymmetry in the front frame.
I used levels, squares rulers on a level floor for alignment (I did tile and
stone for ~14 years). All joints were tacked, then measured and bent/tweaked
before weld-filling, I had to cut a couple of tacks and start them over.

it will be interesting...
