Yep. I gave up on trying to eyeball the lateral adjustment on
planes when I first started using wooden planes, and now I adjust them
all by touch. I hold the plane with the pads of my index and middle
fingers under the plane and spread so they touch the iron where it
extends from the sole.

Needless to say, be careful. The iron is (or should be) very sharp,
and injury may result if you are careless.
