Column base ways being ground in one set-up to insure
parallelism.
Base ways flaked with crescents before
scraping & then colored with Prussian blue.
After column bottom ways have been scraped
to mate with base ways, column vertical ways are ground all in
one set-up.
The spindle housing ways are then
scraped to mate with the column vertical ways. Notice the dial
indicator clamped to wheel adaptor & swung 360 deg. around to
verify perpendicularity to vertical ways.
Beginning of bluing on spindle housing
to column vertical ways
The table and base longitudinal ways
are both ground on our way grinder & then the table is used as a
master to scrape the base ways to mate since it is longer.
Finished machine
Vertical way covers were missing so we
fabricated new ones from stainless steel.
