LOL!!
I just read that post and it is funny that my only scraping experience is also with large babbit bearings. In my case the main shaft bearings from old Navy Destroyers when I was aboard a tender in the Navy. We would get the bearing halves from the foundry, machine and then scrape the lands where the two halves came together. They were then assembled and set up on a horizontal bar for boring. I still have a few of my scraping tools from back then, each person made their own. Scraping babbit is much different than scraping good steel. The idea is the same but if you take too much in one spot from a lathe bed, you have to bring the rest of the bed down to that level.
I guess this still is not an answer to your question; it’s easy to start running down memory lane. I may have an old text book from the days when scraping was done if I find something I’ll let you know.
