<VV> Micrometers vs. Plastiguage

[Mark Durham]

Daniel, plastiguage gives you a reading for one side, but would measure
twice that if you measured that thickness.

I use plastigage all times but, have a concern about both ways. If
rotating member is resting on bearing ( 0 clearance ), the plastigage
measures the total clearance, same as a micrometer... isn't it ?This
means, at least to me, that, if plastigage and/or micrometer give a
total clearance of, say, 0.002", in fact when rotating there is a
clearance (or oil film around) of 0.001"... isn't ?
Just trying to have this clear on my mind.

<< Yes, the Plastigage measures the clearance between the  rotating
member and  the bearing while the micrometers measure and include the
clearance on
 both sides.>>
