I've seen some forums where hermaphrodite calipers are used for marking round stock in a lathe while it is rotating. Having to set it with a rule and using layout dye prior to marking.
I've also seen some discussion about using a dial caliper (or perhaps a vernier caliper) to mark the same. Although over time this may damage the caliper.
Also have seen discussion about using a surface plate with a height gage to mark it up as well.
My question is: Is there a more correct way to do this especially when teaching a shop course to students?
