Threading a threadless steerer

Hi folks,

I have a 26" wheel travel bike (retro fitted with S & S couplers) that was built with 1" threadless fork. I fly it to many 3rd world places and plan a SE Asia tour early next year. My concern is for the replacement of 1" parts - fork, headset and stem itself. These items are not common in the US and probably nonexistent in most other places. In reality such problems are not beyond reality. I've already discovered a lost head bearing on arriving in Salvador after TSA's mucking in my S & S case. It's pathetic that clear covers are sold for bike cases to keep the morons from tearing apart your baggage.

My thought is to cut threads onto my 1"fork steerer and refit an old tech headset and quill stem. I can mic. the OD and ID on the steerer and find a shop with an old tool set. I guess my question is if there is enough thickness in the threadless tube to cut threads. If not feasible I'll try to find an old MTB fork, hopefully with mid-fork attachments.

Another minor issue is that the threadless fork is more difficult to pack due to the extra steerer length (built for a tall frame). It only fits into the case diagonally across the corners. A cut-down threaded fork would help packing.

Then, other than a 10-speed drivetrain, I would have a fairly compatible bike for anywhere in the world.
