I love those who are chiming in. Like I said, my small brain could not figure out a way to save and use these.

I also love all the speculation. Like when I actually hold calipers and then there is doubt on measurement.

Yes, the top was crudely hacked off by some kid with zero hacksaw skills. Somehow in his ace machinist skills he left some threads.

No, nothing was broken off. This is a tall steering tube. I doubt it was available any taller.

I'm sending it north to have it professionally assessed and see if anything can be done.

I wish it was as simple as having a new steerer welded in place. Zero people are willing to do that anymore due to insurance regulations.

Lastly,

Yes, Greta is a good sport.
