I want to measure the width of a groove which is only about 3.5mm wide

Ordinary Mitutoyo calipers with pointed tips are not much good for this
application due to the shallow nature of the groove.

Any suggestions ?


If the profile of the groove is rectangular (or near enough) the
technique I was taught was to measure with, and express the result in
units of, strips torn from Players No 6 packs

I must be very slow on the uptake. I saw the thread title "measuring devis"
and I thought "what's a devi (*) and why is someone measuring them?"

It's only just dawned on me that "devis" is supposed to be "device" :-)
