Hobby,
Are the ways on your mill already worn out and need to be scraped?
Don't know if they are actually worn, but these cheap Chinese mills aren't scraped or even ground, I think. I do know the column is a little out of square to the base, so I think it will be a fun project to scrape everything to a tenth or so and see what kind of mill I can build once I epoxy-granite the whole thing.
I bet I can get it about as rigid as a BP, but who knows. That's why I'm going to try.
