How to "un-strangle" a seat tube?

I would just use a shim and cover it.

On a side note, I wonder if you could use a brass instrument repair kit for this. It's for a trumpet or trombone that's been dented and it's basically a steel ball that you put in the tube and a really strong magnet on the outside of the tubing and you essentially roll the tubing back to round with the ball inside.

About the brass instrument repair kit, I found it a super clever approach! I didn't knew such a thing was for real, thanks for the info. Now, the frame being steel, handling the magnet holding the ball inside the tube could be a fun thing to try out :)

It most definitely would be interesting to try. I had an Reynolds 853 frame that someone did the same thing too. Had I thought about it I would have tried it out instead of recycling the frame because of how thin the tubing is. I wouldn't try it with something with thickish walls but anything thin might be fair game.
