I think I had that same picture in the back of my mind. But the reground cams I have purchased didn't look like that. They looked just like welding reground. Maybe they were polished after being nitrided or something?

We'll learn.

When the hardening on the cam (however it got there) goes, you are right - things go quickly. A machinist friend showed me a 911 cam where the oil spray bar hole had gotten plugged. The cam was worn down to the base circle, except for two paper thin perfect cam profiles on each side of the lobe where the rocker did not contact it. Very delicate, they were. It happened in a day or something like that, supposedly. Of course the lack of lubrication had to have had a hand in the speed of the wear.
