Interesting. Thanks.
Did it get dry? A little galling maybe?
I'm not criticizing. I'm trying to learn from what I see.
MarkCo's comments are interesting,too.

Im trying to learn too, no worries. Just keep in mind im no expert. Just sharing what im doing in the hopes i get some good advice and others can learn from my experience.
steel tool. Did not get dry as best i can tell. The lapping compound was kind of a thick paste. Had to mix it up. Had separated. Looked like it had grease or petroleum jelly in it from the consistency. I worked in about 10 second passes. Applied fresh compound each time. Im wondering if the 320 grit was too coarse. Also i think wheeler uses silicon carbide, which can embed. Apparently there are non embedding lapping compounds, which i would consider if i was looking to try this again.
