More Info:
I really wanted to not only make this bike a "do it all", comfortable to ride bomber, but also spread my home mechanic skills a bit. So I rebuilt or replaced everything possible on this bike whether it needed it or not. Once the frame was stripped, I sealed all tube openings with FlexSeal tape and filled the inside of the tubes to soak overnight with EvapoRust, and then FluidFilm treatment. I swapped the headset with DIY hardware store fittings instead of expensive pressing tools, replaced the loose ball bottom bracket with a sealed unit, and rebuilt the hubs on the craigslist wheels.

Very nice build!
Can you comment on converting a triple crank arm to a compact-style crank setup? Considering doing this for one of my bikes.

Sure - you'll just need single speed chainring bolts since the original bolts will bottom out without the thickness of the third ring. Dial in the front derailleur limit screw so you don't push your chain off and you're good to go! Nothing wrong with a triple but when I don't need the extra high gearing I prefer 2x as it just feels neater and simpler.
