• so I made a "dorn" (translation needed) to fit the inside of the steerer within a 0.1mm tolerance

    I think "Spigot" is as good a word as any. I've extended a Moto Guzzi kickstand and a set of Easton Attack tri-bars with the same method.

    Did you go for 0.1mm clearance or 0.1mm interference fit? I'd have gone for the latter if welding, the former for brazing.
