This is my first crack at scraping a part – I chose the table top of my mill because it was in need of having the first few 100’s of an inch scraped off anyways. Plenty of material to practice with incase I mess up.
The beginnings, a rusty neglected milling table <before I bought this mill mind you>.
The Beginnings
Time to give it some new life with some Wd40 and steel wool. Alright so far

I lapped the table with 220, 320 and 600 grit sand paper, but still had some deep dings to get rid of. So scraping seamed like the best option here.
Start Scraping
4 cut, or 2nd double cut later I have successfully broken up the surface. My technique still needs work because my strokes are too long, but I am getting better at it so by the time I get comfortable with it those deep cuts in the table will be gone.
4th Cut Done
A few close-ups of today’s work.

Disclaimer:
I do no suggest people start scraping machinery with out proper knowledge, equipment and some experience. Even though this is my first real part I have been practicing on some scrap metal and on a cast iron angle plate. Read at your own risk.
