Detailing the strip, clean, and reassembly of this bicycle. The bike is a BGA, which stands for Blanchard-Grange Armes. It was made in St Etienne in around 1935. The derailleur and brakes are ”Velectrik” which seems to be the house brand of Blanchard-Grange. The most interesting thing about the bike is the rear deralieur which is operated by a long leaver by the downtube, which in turn is linked to a rod which moves the derailleur CLICK ON THE PHOTOS IN EACH POST TO SEE THEM FULL SIZE.

Reinstalling the bottom bracket.
1/4 inch bearings required
The adjustable cup and lockring before cleaning and repacking
After cleaning
First layer of grease with 11 1/4 inch ball bearings packed in.
Another layer of grease on top
Drive side of spindle (I hope, this side was a little longer) with a layer of grease and the 11 1/4 inch bearings packed in
Another layer of grease on top
Adjusting the adjustable cup was difficult because;
1. it has wrench flats instead of pin holes
2. the wrench flats are too large for any non-adjuctable wrench I own
3. the lockring notches are too small for any lockring tool i own.
The wrench flats are 1 1/8 inch (28.575mm). I ended up using an adjustable wrench, and since this is not put on tight at all, it worked fine.
After a lot of searching and trial and error, I found this VAR - 78 tool worked very well on the knurled edge of the lockring.
I haven't fully inserted the cotter pins yet, but wanted to see it look a bit more like a bike. Quite please with how the chainring/cranks have cleaned up with the evapo-rust. (the cotter pin nut and washer are in there now)
