[SEL] Babbitt Lapping Compound

[Richard Strobel]

  I would think heavy scraping at first and then lapping compound for the 
final, similiar to what they do with a valve.

JB and others, Would you consider using this compound in a grease cup?

This (or similar) was around here, in Australia, in the 1950s when I was
an apprentice in a powerhouse.

The old tradesmen preferred to hand-scrape the white-metal (babbit)
bearings, which they could do much more quickly. However I experimented
with it later when I had a power house of my own, but it was slow,
especially as I took special precautions to wash all remnants away
afterwards.

I believe the abrasive material was pumice.
