Concluding the work on the column ways:
Rear ways, left side
It is important to be conscious about scraping straight down (in this case), so to maintain the parallelism to the front flats along the width of this way surface. I used both a micrometer and an indicator and more..) to get validate my measurements.
The wear pattern is as expected, and the hold down plates that ride onto the rear ways are probably more worn.
Note: at 05:45 in the video
Made a groove in the 90 degree transition between the ways an the milled area below. The hold down plates doesn't go that far down, but anyway..
Use of a mirror was really helpful to get a good view!.
