    I am not sure as well if I understand the problem correctly or not.
    First, I would check if the run-out is repeatible in position and magnitude with separate mountings.

    I would say definitely not more than 4000.

    When you move it, I strongly suggest you remove the overhead motor first. If this is not an option, at least widen the base by bolting the longest pieces...

    I expect that the shipping costs would be significantly higher than the selling price.
    Take at least also a end-view picture, so that one can see for what type of ways it was originally made.

    At least some of the large ones of the Hendey lathe at Tuckahoe, instead of a true ball have a U-shaped piece of sheet metal with the bottom of the U embossed to simulate a ball.

    I suspect that the missing part is a ball or a domed piece of sheet metal acting similar to a ball in ball oilers (i.e. to keep the crud out, push in with the tip of the oiler when filling it).

    Do you have any sort of recoil buffer to stop the rear motion of the bolt? If so, I would first investiga if, by any...

    This is pretty much drifting from the true topic. Probably triggered by a few things implicit in Jeff's first description. First, when you're cutting (or, in this case, expect to cut) an even TPI...

    The big difference between a bent/off-center spindle and "wobbly bearings" is that i the first case the eccentricity is perfectly timed with the spindle and you can indeed correct it by re-machining...

    I second the suggestion not to weld on the part: it's a fairly thin, slender high precision part, which is the core of your mill. You deform it even so slightly, and the spindle will bind in the...

    B&S straightedges have vertical tabs to which the wooden "handles" are attached with screws running side-to-side, not vertically.
