Dial Test Indicator Pointers
In article , BottleBob says...
Some indicators used to be made with involute "balls" (sort of pear
shaped tips) that automatically corrected for minor cosine error. But I
haven't seen any in years.
Federal's electronic gaging heads still come with that
feature. Works well.
