Yes. the supplied holders fit the same in both. In others words the
travel of the locking bar is about the same, regardless of which of
the two sides I use.(About 90 degrees, regardless of the supplied
holder I use).

Ok. With the tool post mounted 45 degrees from square(diagonal),

I was just going by how it would have to be positioned in order for
the locking bar to, as you said, *point toward the tailstock in the
unlocked position and toward the operator in the locked position.
(Don't worry. That is not the way it would really be mounted). :-)

* * * * O.K.

The first two pics show the toolholder in it's proper relative
position opened and closed. Open would be more like 1:30 and closed at
7:30. (At about 5:00 I can still slide the supplied holders on).

(the rods should be bigger, but that is the biggest that I can show
using ASCII graphics.

* * * * Anyway -- place the rods into the Vs of the dovetails, and
measure the width across the outside of the rods (using a caliper or a
larger micrometer).

* * * * The measurement across the rods should be close to the same on
the two dovetails. *If it is not so, then one of them is improperly set

I'm not sure what "close" would be but I just measured both sides with
a ruler.

* * * * I'm talking about measurements with something which reads out in
0.001" increments or better.

* * * * *And the measurements are 1-21/32" on the right side, and
1-2/3" on the left.

* * * * What kind of ruler do you have which reads in thirds of an inch?
And if that is correct, they are just a bit out. *1.6563" vs 1.6667"
(giving fractional sizes with different denominators leads to confusion.
