Machinist lathe parts??

Got a few of these round bars at an estate sale with a bunch of scrapers, they were only $1 each so I knew it was worth the gamble. Was wondering what these round steel bars were for.

Without knowing the length it looks like a straight bar to align the tailstock with the chuck using a dial indicator. Tony

The bars are 14 inches long X 1.5 inches.

It could be a number of things. Maybe a bushing driver, or a go/no-go gauge, or as Tony mentioned, an alignment shaft.

You're right it could be anything. I thought boring bar. It does have a cut down on one end like a bushing driver. The countersink on the end would be for the center point on the tail stock. That's why I thought alignment bar. A straight bar can have many uses. Tony
