that's backwards from all the other Aloris holders I've seen - maybe if you
just disassemble it you can reorient the handle assembly by 90 degrees (and
clean all the swarf out of it while you are at it)

Just loosen the nut and rotate the entire block. You are un-screwing
the bar that locks into the slide. You mount it that way.

Is the problem that the handle turns too far, or not far enough?
If the dovetail in the holder is too wide, the handle has to turn
farther to clamp. Same if the toolpost dovetail is worn, but it would
be unlikely both dovetails would be worn the same amount, and the
amount of wear that would place the handle over the work would be
The problem is worse with my import tool holders, the handle hits the height
adjustment screw as its tightened in the boring position. I was guessing
that there was a way to dis-engage the handle, rotate it, and re-engage,
guess not. Another reply said it sounded backward from his experience, in
fact this is on a toolpost mounted on the back side on a CNC attachment. If
I need to I can shorten the height adjustment screws to clear the locking
handle. I just thought it might be an easy basic setup adjustment that I
hadn't figured out.
My experience has been with BXAs mostly, and a bit with AXAs,
but let me ask something first:
Is yours a piston type or a wedge type holder? The piston types
have two locations where it should lock, and the lever (with nothing
mounted) can rotate a full 360 degrees.
For the wedge style, it mostly matters how you have it mounted.
The two dovetails should be one to the left (for normal turning), and
one towards the center of the lathe (for facing and boring). I try to
make sure that the inner dovetail is parallel to the axis, and almost
never rotate the post to get other angles. That is dealt with by the
selection of tools and tool holders.
If the dovetails are in the positions I suggested, and there are
still problems, it is possible that someone took it apart and
reassembled it with the wrong lead started. The collar rotated by the
lever has a multi-lead thread, and you would have to disassemble it and
reassemble it with the right set of threads engaged.
If there is something different about the CXA -- please let me
know about it.
