What is it?

They're used on milling machines rather than lathes, AFAIK. Though if you have a milling attachment they'd be useful. I was taught to use them to find edges in the milling machine. Here are a number of links for YouTube videos of several kinds of edgefinder, and how they're used:?https://m.youtube.com/results?sp=mAEA&search_query=Usung+an+edge+finder+in+milling I even misspelled "using" and got several good results.??

Physics doesn't care about your schedule. The only reason I know anything is because I've done it wrong enough times to START to know better. Expect in one hand, expectorate in the other. See which one gets full first.

I got this by accidentally. It’s called a center finder or non magnetic separating rod. It does split and is held together with a spring in side. Is it related to lathe work and how is it used?? Thank you From Louis R Vallee |

That is a edge finder. Mostly used on a mill. There are YouTube videos on how to use it. Basically, you mount it in your quill or chuck. Spin around 1000 rpm. When the small end of the part touches the edge, it will kick out a bit where the spring holds the two parts together. You now know where the edge of your part is after compensating for the tip diameter. If this is imperial size, that small tip should be 0.200" diameter. That mean you are 0.100" away from the edge. Do both sides of the part. Divide by 2, you will have the center of your part.
