Early 1900's J.B. Spencer lathe project

There's adjustments on the spindle on the head stock just don't over tighten . A pin spanner may be needed to do it . I'm sure it's letting the spindle travel sideways as it's turning . If you lift up on the spindle will it move up or down ? I too think it's a wood lathe .
 
Thanks for suggestions... Got back into it today.

Sbullet I thought I had the headstock adjusted the best I could but you got me thinking. There is a threaded bolt sleeve at the back of the headstock. I could never budge it at all and did not want to break anything. The two other nuts on the outer tube I could move. Those nuts move the spindle fore and aft against the front bushing but could not really get the spindle tight. Seems like the adjustment ran out of taper.

After looking at it for a while I want to give the nut on the back end another try. Sprayed some penetrating oil in the tube. Put the whole adjuster in the vise, got a pipe on my wrench and was able to get it free. Cleaned and lubed everything and put the headstock back together. Was able to get the spindle now nice and snug with zero play. Really looked promising.

Fired up the motor and It still had a wobble. I thought I was on to something but I guess not. I can not move the spindle at all everything is good and tight.

Brino... I chucked up a 18" round stock and could not move it. Of course when I powered up the machine. Still had a "1/16 of run-out.

With the chuck off and lathe spinning I can see no visible oscillation on the spindle. When I hold a tool at the spindle threads I can see just the slightest oscillation.

At this point I'm not sure what I will try next. Maybe take a closer look at the headstock bronze bushing? I guess the spindle itself could be bent. If that was the case could the spindle end be machined true and new threads be cut? At 1 1/8" could it be turned down to 7/8 or even 3/4? Anyway tomorrow's another day and open to all suggestions.
