Use the hack wheels and convertor I did for a couple of months- if you really want to DIY it & can be arsed then disasemble a cassette to get the cog you want / buy a Shimano DX cog and use cassette spacers (from your unfriendly local bike shops' discarded cassettes?) to space it out and get the right chainline - lots of info on the web..
Offer! - I actually have a 26" rearwheel done as above with a DX cog + well-used Schwalbe City Jet tyre on it + used chen-shin cheapo slick spare + spare new tube - £10 if you can collect from Shepherds Bush / HSmith (weekends only).. No worries if you reject me and want to do it yourself - I UNDERSTAND. ;-)
