Yes, but then you have to bring the point over the mark. I find that
challenging without the magnification. Even using the other center
finder (this one, so there is no confusion:

the alignment of the two parts of the barrel are tricky and much
easier with a magnifying glass.


When I use the pointy end, I feel the joint with my finger nail. It is easy
to tell if it is overhanging or under-hanging a small fraction of .001"
