Re:
I quick sit rep. I have tentatively started to strip and overhaul the BSA. The brakes are cleaning up OK. Calipers are a little bent but I think straightened out OK. I've not gone to town polishing the alloy just yet.
I've managed to get both the cranks off. Chrome is obviously shot, but they are a fluted BSA set. Quality, once upon a time ... ! The teeth on the chainwheel are worn, but I don't think they are worn out.
Front wheel hub cleaned up OK, spokes are good too. Steel rim is horrible. It's not rusted through, but it's so deep it will chew through brake blocks pretty quick! I do have a set of lovely Alumlite rims I saved from the tip for a fiver. They have rusted out spokes and the hubs are toast, so might be a good idea too brush up on my wheel building!
I've stripped and rebuilt one pedal. It's gnarly and the cage bent. I've straightened it up as much as possible, regreased the bearings, which were actually pretty good.It's a bit rattly but I've ridden worse.
As for the frame, it's nasty! I leave a trail of flakey paint and rust every time I move it ... I've attacked the forks with wire wool so far. They don't look any better. The frame is much worse than the forks ...
So, a little progress. I'll try and get some photos up, but so far it's not been very photogenic!
