That was great, Angus. Sounded so good I had to put in the second ear bud to fully appreciate it. Also, while maybe common, it was interesting to see someone else sticking their finger in front of the hole in the return tube to verify flow (and color, I assume).
I admire anyone who is organized enough to work on their bike in a small shed. During my current work on the barn-find A7, I've taken over my wife's parking spot in the two-car garage for spring, summer and fall. This in addition to the other half of the garage that I've greedily occupied for years.
