Was this ever even ON-TOPIC?
It appears from the beginning to be basically a general bicycle mechanics thread which is covered quite well by at least two other websites that have forums for bicycle mechanics for bike vintage and new bikes. Took a slight turn to ON-TOPIC for a post or two and then went OFF-TOPIC again.
If this had been a topic from the beginning about taking a vintage frame and reaming it up to todays common diameters, etc. in order to fit newer headsets -
then you wouldn't have heard from me...
