Some progress, chiefly swapping the front wheel (because dynamo - I'm doomed to have mismatched wheels) and rear tyre (and rim tape, because the the plastic stuff looked iffy and I had some 19mm Velox right there), fixing the p*nct*r* I somehow managed to inflict in the process, fitted mudguards, adjusted the headset (considerably less painful due to the availability of FRIKKIN LAZERS to determine when the wheel was straight) and brakes, fitted the lights while waiting for the glue to dry on the tube repair but haven't done any wiring yet. Kickstand appears to be slightly too long, which is irritating (but admittedly less irritating than it being too short). Managed to b0rk the quick link on the chain, on account of it being non-reusable, which is pointless. Reusable ones on order. Noted the absence of any V-brake mounts, which means I can't fit the parking brake. Have molished a Mike-Burrows-compliant hydraulic disc brake compatible substitute for now, and will keep an eye out to see if that external latching lever thing that Hase came up with a couple of years available might be available as a spare part.
I have at least had plenty of practice fitting and removing the Rholoff wheel. This, at least in this incarnation, is the benchmark for-low faff IGH.
