    Smile Rereaming the tail stock

    Hello All
    I am a newbie home shop guy. My tail stock quill needed to be replaced the guy who owned the lathe before me spun something in it. The replacement quill is not the best either. When I tried aligning the tail stock it is .015" high. No torquing that amount out.Therefore I was hoping I could purchase a MT#3 reamer place it in the headstock spindle and re-ream the quill aligning the tail stock (quill bore) with the spindle bore?
    I have leveled the lathe and checked the headstock alignment with the ways everything is good to go. When I using the old quill I was able to align the tail stock .0015" high, fore and aft dead on. The newer MT#3 quill bore is what is off. Any input appreciated.

    I was wondering why that was here in the Gunsmithing area.

    The short answer is, no you cannot do what you are discussing.

    The morse taper reamers are find for hand use, to remove a smudge or
    high spot that a spun drill or arbor as raised. But they cannot be used
    to alter the center position of the taper in a tailstock ram.

    Your best bet is to use the ram that is on center, and try to clean up
    the socket with the reamer, BY HAND, not under power. If the tailstock
    center is badly off the spindle axis, inspect the tailstock carefully, there
    may be shim between the two parts, if has a lower base.

    Muley,
    Take the quill and put it in a true three jaw or a four jaw and indicate the OD in then check the ID.(the taper)If your within a couple of thou. this is not your problem. Maybe there is a chip inbetted in the ways of the tailstock .check it if so pick it out and stone the surface smooth. Check the underside ways first gotta be something under there!!!
