Mattison Surface Grinder Rebuild

	To the left is an 18'' x 72'' Mattison surface grinder to be partially rebuilt.
At the right can be seen the Mattison grinder partially disassembled.
	To the left is the base of the Mattison grinder on our way grinder. The ways were progressively ground of a period of five days in order to let the casting stabilize. The fourteen foot long ways had a T.I.R. of .0002 when finished.
To the right can be seen the finished ground base after leveling. Micarda was bonded to the bottom of the table ways after machining. The table was then hand scraped to mate with the base.

	At the left is the spindle housing with motor. It is set-up by checking the spindle perpendicularity horizontally and vertically with a granite square on the table and indicated parallel with the table travel. The dovetail ways were then ground.
To the right is the finished ground spindle housing and ways.
	At left the spindle housing with newly ground ways is mounted on a forklift and used as a master to scrape the cross ways of the vertical housing or saddle. This was very time consuming due to the inaccessibility of the cross ways.
