Nice work!
I think I have this set up well enough, I may end up drilling and tapping the middle ring and running some short screws through from the outside of the ring to give the chain some pegs to grab onto to climb out of the granny ring better like so many modern rings have, but I need to ride it first before messing with that.
This cottered crank was actually about as good as a guy could hope for for this modification as the middle/big ring spacers could just get replaced with the tripilizer.
