    This is what I'd do with it, at this point.

    I've always mounted on the back of the lathe, it's out of the way and easy to attach a bracket to the back of the saddle to drive the read head, mount a long stick of aluminum angle over the top to...

    Not familiar with the earlier headstocks, but later 9's have shim packs that can be "adjusted" (remove shim(s)) to obtain correct clearance. You checked by lifting up with a bar through the spindle?...

    I've bought all my thread mikes off Fleabay, mostly Starretts with a couple Scherr-Tumico.

    Good buys can be had if you're patient, I've mostly paid $40-$60 each, a fraction of new.

    You want minimum .020 over bullet diameter.
    My experience is that overbore isn't as critical to performance as some think.

    Bob Pastor's "Viper" fixture is pretty much the standard bearer for this.

    I can appreciate the old american iron "syndrome"- with SB and Sheldon lathes, and an old Steptoe horizontal that had been converted to vertical.

    To clarify, this was converted to vertical (probably 1970's or '80's) with a Tree head- so there is no existing drive unit; the original spindle and drive shafts are still there but no pulleys,...

    Thanks for the input, gentlemen.

    After taking another look at this, I'm thinking it probably makes more sense to work the other end of the table.
