A few images after the restoration.

Now, if your frame is already cracked in these areas, it would have to be your call if welding up the cracks and adding rings would be safe. I felt confident on my bike as I did not have any cracks yet.
Understand: Aluminum has a finite life and it is just a matter of time until it will begin to fatigue.

After letting it cure over night, I primed and painted the rings.

After measuring the head tube, I realized it was not perfectly round due to distortions when the frame was originally welded. So I decided to fit the ring to the tube instead of having the inside diameter of the rings machined to fit. I used a sanding drum chucked up in my drill press set to the slowest setting of about 400rpm and worked it down to about a 0.1mm smaller than the tube diameter.

Thanks..
