Tool identification help please.

So you use them as leverage between two jaws to twist the chuck loose?

George, if you look at the photo of the chuck I posted you'll see the body is in two pieces, each has a hole to receive one of the tommy bars. As the two parts are twisted in relation to each other, the jaws will clamp or open.

The outside rim of the chuck will have holes in it and the rotating ring that tightens the jaws will have holes. You insert the bars to increase leverage enough to get the chuck tight. If you post a picture of the chuck I can confirm they were meant for that chuck.

one of those parts is physically the same piece as the thread that screws onto the drive shaft spindle; by locking the spindle, you can use the tommy bar to turn that one loose (turning the other part simply opens or closes the jaws)

Ok so these must go to another chuck. Not sure if that one was buried somewhere or what but the one I got with the lathe is a nova. It uses an Allen wrench.
