So I have a department store bike from the 1970s that I picked up a few weeks ago and once I got the quill stem out (using all the tricks I learned from here) I found several gouges on the steerer.

I don’t really understand what they’re from because the gouges are on the outside with dents on the inside of the steerer? Were these caused by over tightening of the quill stem? Also, this is not safe to ride right? It is steel but it’s gouged (with some dents) in several places all around the steerer. Is it fixable at all?

There were so many gouges that I had to number the pictures to keep track of them but I tried to take pictures of the outside and showing the corresponding inside dents.
