Just got a Phase II tool post piston type. I like it a lot but I see
the difference with it's repeatability. You have to hold the tool
holder in position the same each time to be as close as you can be
before you tighten it. Not bad though but the next one for my other
lathe will be a wedge. Anyway, it has a threaded hole in one side of
it. This may be a dumb question but, what is it for?

Are you talking about the threaded hole for the height setting? Maybe you're
missing the knurled knob and that's why it's not repeatable for you.

There should be a studf in that threaded hole with a nut, washer and a
knurled nut as well. Once the tool height is established you lock the
hex nut against the knurled nut after contacting thr top of the tool
post with the knurled nut. That gives repeatability on height. Sounds
like you maay be missing some parts for your tool holders. Most I
have seen even the import knockoffs of Doprian and Aloris models have
3/8"-24 threaded studs........which you can pick up at Lowes etc in
the special fastener boxes they have in the nuts and bolts department,
or even HD. I would double check to make sure they are not metric
though. You can also get mny for now with just two hex nuts, and make
some knurled nuts to fit. A good project on a lathe is making some
knurled nuts.

No, there is a hole on the right side of the tool post about half way
down. Looks like something screw in it.

As mentioned in previous answers by various people to the same question: the
purpose of that hole (the one on the right side of the base block-- not the
one for the adjustment nut in the holders) is to attach a stop. Say
you're doing minor production work and feeding the stock through the
spindle. You have a carriage stop on the right side of the carriage, and
possibly another one on the left side of the carriage. This stop is for
adjusting the stock. Move the carriage to the right against the right-hand
stop, flip the toolpost stop into place, push the stock through, tighten the
chuck, flip the stop out of the way and on to the next piece.

This hole is in the main body of the tool. All the parts are there and
the hight adjustments work. I was just curious. Maybe it is for
mounting something. When I said the tool was not repeatable, I meant
you can move the tool holder back and forth and then tighten the
handle and it will stay in whatever position it happens to be in. You
can move it around a good .020. It does not really matter for what I
do, but since it is a tool I will probably use for many years, I think
it is worth getting the better wedge style for the little extra money.
I am not a tool junkie, but I like nice stuff, and I was just a
little disappointed in the tool.

So get in the habit of always pushing it to the right before tightening.
It sounds to me like your toolholders female dovetails are cut a bit too
wide. You can tell by putting 2 1/4" ground pins in the dovetails and
measuring - for AXA size that dimension should be 1.000". - GWE
