This is a project that is intended for next winter. I've mentioned it a few times and it's coming along slowly, mostly because I am a tightwad and don't want to throw lots of money at it.
craigslist find Peugeot UO14:


I have a Sturmey-Archer AW 3 speed hub. Using a technique published by Sheldon Brown, I am planning to install 2 modified Shimano cassette cogs on the hub (14/24), and 2 chainrings on a touring crankset (38/28) which will give me 2 "ranges", high and low, with 3 speeds in the hub to make 6 speeds. The two ranges both wrap 52 teeth, so chain tension will be no problem. I think I will use wing nuts on the rear hub to allow easy shifting. The chain will have to be hand-shifted, which is fine because the point is to have no derailleurs for a clean look and no icing in the winter. I also have MAFAC Racer brakes and some "Randnner" bars. I just need a dark ano Matrix rim to build the rear wheel.
