Hey buddy,
I took it to the local framebuilder (argos cycles) who did it all for me (I think using the sheldon brown method). I didnt want to risk messing it up. £30 it cost me.
Although I have just tried doing it myself to my brothers hack bike. He needed the forks spreading so we took a car jack to it and widened it. Slotted the wheel in and fingers crossed hope it holds.
