Just a follow up on this one -- did an end-to-end overhaul of the hub one more time and it is fantastic. Very smooth and solid as a commuter bike. The overall project looks like this:
- Old Raleigh Robin Hood Frame
- Rebuilt 700c wheels with alloy rims
- Single brake in the front
- 1989 SA 3-speed coaster brake hub in the back
Very smooth and durable. At some point I may swap out the cottered cranks for square taper ones, but for now the bike runs great.
