Another laser finder.

This is a more elegant version than to put a pointer in the mandrel or a chuck with just the extremity eccentrically turned at a decimal diameter on the lathe, and less easy to loose in the workshop than something looking like a pencil(I'm using the third version because that)…

Yes, I have been thinking of doing that but it might be a little while before I get around to it. i already have a pile of other videos that i need to edit. There are videos on Gelbart's site that is referenced earlier in this post.

Dan is a smart cookie, self made billionaire as well.

Dan is a smart cookie, self made billionaire as well.

And he's unusually humble too. There aren't many billionaires who choose to make instructional videos for people to learn about machining!

Well I am a bit disappointed that nobody spotted my "deliberate" mistake with the clamp. As displayed in my original post and as I first made it, there were 4 points of contact, but of course that never works correctly. Only 3 points will be gripping properly, the fourth will be either not even be touching or gripping with minimal force. I am usually very conscious of these things and I don't understand how I made that mistake. It just isn't like me. In practice it worked fine but the purist in me wouldn't let it drop until I fixed it

Late update to show how I fixed the four point mounting.

I cut back two of the original four contact points and added a flat head screw for a third point. I am much happier with it since I did that.
