Well, the project is near completion. Only a few missing bolts (gold star if you can find them in the pics), brakes pads that desperately need adjusting, and a new saddle (any suggestions?)
I've included too many photos here, but the duplicates are provided to show how an overcast day can soften imperfections, while direct sunlight exposes everything! The pics at the beginning of this thread hid many of the rough edges because they were taken in shadow, not direct sunlight - and honestly, by pics alone, it doesn't look like much has been improved upon!
At any rate, here's the product of my labor of love, or stupidity, or whatever you wish to call it.
Thanks for all the help and advice, and thanks for reading. By the way, the Sturmey Archer hub is working flawlessly -- at least for now!
