Flatness gage

An apparatus for measuring flatness of a surface comprising:

• a locator block slidingly engageable with a slider block in a first direction,
• a height measuring means with a linear probing means, said height measuring means mounted to said slider means,
• an alignment means for limiting relative motion between said sliding means and said locator means to said first direction when said slider means is engaged with said locator means,
• said locator block having a top side and a bottom side wherein said slider block is engageable with said locator block on said top side,
• an elongated aperture is disposed through said locator block,
• said elongated aperture elongated in said first direction, and
• said linear probing means is positionable through said elongated aperture.

An apparatus for measuring flatness of an Almen strip holding surface of an Almen strip holder, said apparatus comprising:

• a locator means slidingly engageable with a slider means in a longitudinal direction,
• a height measuring means with a linear probing means, said height measuring means mounted to said slider means,
• a centering means for centering said probing means substantially along a longitudinal centerline of the Almen strip holding surface extending in said longitudinal direction,
• said centering means including an elongated aperture generally centered along and disposed through said locator means,
• said linear probing means is positionable through said elongated aperture, and
• an alignment means for limiting relative motion between said sliding means and said locator means to said longitudinal direction when said slider means is engaged with said locator means.
