I have one of those gizmos. Works fine, but not NASA approved. ;) I haven't tested it against the edge finder +1/2 diameter of work + 1/2 diameter of edge finder since I haven't needed that precision, but it's better than my eyeball and it's quick.

Lol I did it I just found the center of my block quick stripe of dykem scribed a line located line spotted and drilled hole thanks for all the replies
 
Mount the rod with V block in vise.
Put flat bottom end mill in collet.
Lower quill until it just barely makes a flat on the rod. That’s the center of your rod. Drill there.

Using edge finder then moving over 1/2 is still better I think. But this works pretty well.

Oh, boy, THAT'S funny! It happens around here more and more. Best part of that is SWMBO is unaware of this development (we hope).
Might make for some awkward conversations later. "Don't you already HAVE one of those:cautious:?" LOLOL. I have certainly been there!
 
I have and occasionally use a center finder like that. It's pretty good within +/-.005". To increase accuracy, I'll usually "find center" from one direction, zero the DRO, approach from the other direction and compare. Then just for fun, I'll rotate the spindle 180º and repeat.
