Another Threaded Hub question
OK - so I've got an old lightweight 531 frame of suitable geometry, horizontal drop-outs, adequate wheels. Decided to go low cost "suicide hub" route - because I've got all the bits and anyway I don't know if I can handle a fixed ( I am a bit of an old dog to learn new tricks

)
Only thing I've had to buy is suitable size fixed sprocket.
Said sprocket is flat one side, raised lip on the other (so that it's deep enough for the threads)
Question - does it matter which way round the sprocket goes? Flat side to the hub or raised lip to the hub? Or can I choose so as to adjust the chainline slightly?
