Progress report:
Homemade scraper:
-----
So I took the table and saddle off the mill.
Saddle:
Table:
The table really isn't that bad, there is some glue starting to peel near the turcite. There is also noticeable wear on one corner - one strap too tight?... Figure I might as well replace it while the process is set up.
Head:

From what I have gathered, this is the current plan:
Utilize ground bars for each of the axes as an interface to apply pressure to the rulon.
For the mating process:
X-axis:
Have rulon machined flat with a flycutter, put in oil grooves, and then scrape/mate to saddle.
--
Y-axis:
Scrape/mate to bed.
--
Z-axis:
Scrape/mate to column. Due to the fact that the contact area is in a vertical orientation, it is crucial that the spindle is square to the column, from both directions.
This will be accomplished using a precision ground rod precisely mounted in a toolholder (or idealy, it will be a cat40 assembly) and a .0001 indicator.
The indicator will be mounted on a magnetic base and touching the bar parallel to the controller plane (y-z). As the head will be moved up and down, the reading will indicate the nature of the axial-y plane. Gibs will be adjusted until indicated measurement is within spec.
Next, the indicator will be touching the bar parallel to the column plane (x-z). " ...... "
Repeat.. etc.

Is there anything that I am overlooking as far as my machine mating staging process? Or any other recommendations?
And thank you to all of my "student-appointed" mentors floating around on PM.
