Old frame, New build

[Dangermouse]

OK so we all know steel is the best, I am wanting to build something 531 or 753 from the late 70s early 80s into a modern (sorry) bike with latest components, my only problem would be the headset, is there a 1" unthreaded headset that would let me use original forks

Threaded fork into threadless headset - bad idea?

My ha'pence worth from my world of bodging. Yes you can use a threaded steerer with an AHeadset. Problem though is often finding a threaded steerer with enough length to use as AHeadset is intended. You can however combine the two headset types as I will explain. Get as long a threaded steerer...

If you are on lfgss they have a dedicated thread for this sort of thing

A framebuilder can extend the steerer to a blank unthreaded column
