Convert 1" threaded headset to threadless?
In general, has anyone ever reamed out the upper threaded cup on a one inch headset and used it on a threadless fork? Is there any rational reason this cannot or should not be done?
Specifically, A Stronglight A9 alloy headset, to be inserted in a 1974 Viscount Aerospace Pro (remember those, anyone?). The OEM aluminum and Tange replacement forks have both been removed and are being replaced with a carbon fork with aluminum steerer. This headset is nearly weightless, and aside from the fork and stem the build will be very old school, down to the OEM sealed cartridge bearings. It would be cool to make the mod and use this headset.
The steel races are removable and will not be affected by the reamer.
The locknut and keyed washer will not be required, obviously.
