I have a Warco Major milling machine and have just bought a set of chuck/collets from Lycorish for £55.29. My problem is when I put the dial gauge on the shaft it has a run out of half a thou very good, but when I move it down to the tool and the nut the gauge goes hay wire there is so much wobble I have cleaned the collet inserts and tried different tools which are brand new but it’s still the same what am I doing wrong Please help as I am new to milling.
