Dial gauges tend to be more convenient in these types of applications, because
unlike the calipers, they are sprung. As one then rotates the job one is measuring,
since the gauge exerts a tiny force back onto the job, the readout they provide
is continuous and it is easy to judge the high and low points.
Brendan kindly mentioned he had machine shop access, so perhaps he might
be able to lend you the use of a gauge for the day?
