Adam,

I tried it on a graphite rod I was redoing. It seems to me, if I remember right, I was trying to line it up through the eyes themselves. That didn't work because of the change in diameter of the eyes. I tried it on the rod itself and that didn't work because of the taper of the rod. It would seem to me that somehow a lasar would work, it just didn't work with me doing it. Hopefully someone with more experience will be able to answer your question. I will be interested also.

good Luck
