Gauge callout on drawing
Gauge callout on drawing
(OP)
I have a drawing with GAUGE attached to two dimensions.
Have not seen this callout before and am unsure what it means. The attached sketch is representative of the drawing. If you can shed some light, I'd appreciate it.

KENAT,
Have you reminded yourself of FAQ731-376: Eng-Tips.com Forum Policies recently, or taken a look at posting policies: http://eng-tips.com/market.cfm?

This method is lot easier to measure with hard gaging during production. We would build a ring with ID at 2.900 dia and a OD of aprox 1" bigger than your OD of the part. Then we would indicate off the surface of the ring to the top of the part. This is lot easier than trying to measure to Thero sharp point.

I would use a profile tolerance and basic dimensions. Your profile tolerance would be approximately .004". Perhaps I would use .003".
The tolerance does not only apply at Ø2.900×.400.

Rather than giving you the start or end point they've given you a point somwhere in between defined by a diameter and a height. The diameter is 'perfect' with the tolerance put on the height.
Often things are dimensioned like this because the nominal mating point is on the 'gauge' line.

More often than not in my industry it's dimensioned like this for ease of hard gaging at the press
