The strut edges receive a thumbnail detail on each long edge.  I used a 3/8" radius roundover bit in the router table and adjusted the bit height until I got the profile I wanted on a scrap of wood (which was the same thickness as the struts).

The JessEm stock guides came today, and I am an instant convert.  These things are great.  They are well-built and feel substantial.  They're so much easier to install and adjust than featherboards, and their canted guide wheels really do a good job at keeping the work pushed against the fence.  I was able to concentrate on alternating-hand continuous feeding without having to worry about the strut drifting away from the fence.  There was slim chance of kickback since I was removing so little material, but the wheels only turn in one direction in order to mitigate kickback if should it happen.  Highly recommended.

In no time at all, the edge detail was done.

Finally, I needed to trim the excess on one end of each strut.  One end already had the correct spacing to the first hole, so I just flipped one strut end-to-end, dropped two connector nuts to index the last two holes in the upper strut and those of the one below, and marked the cut line. 
Once all were trimmed to length, I set them aside until it was time to sand.
