I got a Hardinge Sjogren speed chuck with a recent lathe purchase, D1-4 mount.
A relatively new Hardinge collet mounted in the chuck has a bit more than .003 runout holding a 3/4 dia ground rod, which seems way too much. The chuck body OD has only .0005 runout at the nose, but the internal collet taper is out that much too. Is there an adjustment to set this more true? I haven't used one of these before, and have not had it apart yet, thought I'd ask beforehand so I know what to look for.
