531 framed fixed gear bike

yo! anyone tell me about any threads re. converting a reynolds 531 with vertical(ish) drops into a fixed wheel bike?? do i need to do anything to the frame to stop my chain getting slack? i just went to brick lane bikes and the woman didnt really given me answer other than "itll cost you £300"...

sorry, i know this isnt the right thread but im new to this and they wont let start my own thread! bastards.

cheers folks

• Get an eccentric rear hub
  
• Get lucky with a half link chain
  
• Have track ends welded on instead of the vertical dropouts.
  
  

Personally I would do the first option if the 2nd looks unlikely to work - If you find you really like fixed riding *then *you can spend money on a proper track frame.

Plus you can always change it back to geared if you ever want to.
