Feeling motivated (thanks, Jeff), I got work making the other rear leaf spring, as well as the remaining leaves on the side I previously started. The eye bending went smoothly, so I removed any burrs after trimming each leaf to length, then rounded all the long edges over slightly to ensure there'll be a small shadow between each leaf:

I also removed the molded on spring saddle brackets from the equalizing beams, drilled out the pivot bores at both ends, and test fit some brass tubing in the bores:
It's always good to make progress.
