Upon seeing RA my first reaction is "can this thing be built min R one bonder" and went ahead to actually work on the required movements.

The track loop for moving salt used to have 3-length simple arm facing northwest and fit snugly with triplex arms. It's be obvious that shifting them to the left allows more space for triplex pipeline to not stretch that long, but it didn't. The arm 16 swing turned out to be unbeated.

Enjoy the stark difference between the two sections and let's see how hard triplex-first assembly at min R really is.
