Hi Rob,

Not quite sure what it's meant to do. Looks like the sort of centre-finder where you stick a pointy bit in the centre-pop and then adjust until the other end stops going round in circles, But they usually have the gimbal quite close to the chuck/faceplate end, so that the far end goes round in bigger, easier to see, circles. Before I owned any sort of dial gauge, I made someting like that once, with a rod through the hole in the end of a (springy) hacksaw blade, to act as a gimbal. The "gimbal" was very close to the point, with 10x the distance on the other side, so if the work was 1 thou out, that produced a 10 thou wobble at the far end. 

Or am I (can't resist it!) missing  the point?

HI all sos for the confusion right this will be used with a 4 jaw chuck as bin sed their will be a center pop mack in the peace being held in the 4 jaw chuck you will put the pointed end of the rod in to the center pop on the job keeping the rod as sort as possible at the chuck end when you set the lath gowning the back end of the rod will be all over the place  adjust the work in the 4 jaw tillthe rod stays still then the work peace will be on center i will post pics  to give a beater understanding as soon as i can
