Micrometer ratchets

[John MCParticipant @johnmc39344]

Not sure what you mean by “deceiving” and “its easy bend the result to fit”?  A measurement is either right or wrong, surely?

I rely on a comparative method for accurate sizing as does industry.

Those that read my last post may have noticed “bore mics” at the bottom of the post, that was a reminder to self, got distracted and hit post!

I use bore micrometers in the range of 1/2″ – 1″.  I find the ratchet on those works very well with regard to accuracy and consistency.
