It is worth the trouble. My worst was 7 years ago an utterly unridable 80's custom from a local builder. Hung upside down by strings looped through the rims the fork would cant off 30º. A lugged Reynolds 753 which you can find Reynolds engineers documents saying 753 can not be cold set. I tried to cold set the fork first and as soon as i mount and moved it would snap back to the original position. Fortunately an old time framebuilder in town with Marchetti frame table and Lange fork table got it perfect. I enjoy it to this day.
