Looking at the bottom of the table, it shows a telltale discoloration from the heat-treating that ostensibly hardened the working surfaces prior to finish grinding. Also note the massive leadscrew.
The ends of the table show similar markings of the heat-treating. Table finish is beautiful- smooth, consistent and even. 
Here we see the scraped surface at the top of the column, where the ram's dovetail/swivel assembly sits. The finish isn't impressive, but it looks worse than it is. To the bare finger, it feels pretty smooth. We'll be checking tolerances later to see how parallell it is to the table.
A close-up of the table ways on the saddle is equally ininspiring, but again, the surface looks worse than it actually is. Not knowing how to scrape ways myself, I suppose I'll have to live with it. But I'll be keeping an eye on table wear over the years.
And another angle. I don't know why it's so seemingly rough, since the underside of the table is so smooth. Perhaps it's an oil stiction thing, or it allows the better distribution of the way lube.
In any case, the table moves smoothly with no binding at any point, so I'm not complaining.
