Old Raleigh 12-Speed Transformed into a Fixed Gear Bike

My friend Bill gave me an old 12-speed Raleigh that, while still a solid, classic bike, had seen its better days. Meanwhile, I found myself with a shorter commute with no big hills that I wanted to do year-round and in all sorts of weather. Voila - I suddenly had a use for the Raleigh and so in a two-stage project converted it into first a single-speed commuter bike with freewheel, then ultimately into a fixed gear bike with rack and fenders, perfect for commuting.
