Threading forks is a pain to do at an LBS because its usually done at the factory with a huge lathe machine with a rolling process. Bike shops only have small die cutters and hard metal, such as chromo, will dull the cutting point. Plus the threads will not be as perfect as those done in factory. In thinking of getting this done with a cream kilo frame i recently ordered, and Im going to look on craiglist for a machinist with a lathe cutter.
