 Perhaps you are right?
I will see how this topic "Pan's Out" before I/we go to far off track. 
Have a good day.

 Maybe the XYZ orientation and story stick stuff should be moved to another 
thread? Curt?DanK

No mud, Curt. I readily prefer the story stick methods you refer to where
everything is laid out from an absolute origin in the left front lower (X,Y,Z)
extremity and from there I use the mathematical orientation for all but metal
lathe work. In fact I have a CAD program with three layers each X, Y, and Z
axis holding a story stick surface upon which to lay out marks for every
feature to be located from the absolute origin. In complex furniture work, it
sometimes helps to have a sub-stick based upon a local coordinate system which
is positioned from the absolute origin. Once the 3D CAD model is complete, the
story stick layers are activated and tick marks applied. A stack of linear
dimensions is put on that layer all coming from the origin tick. Those stacks
are used to lay out the actual stick surfaces. If done well, this can save a
LOT of time when using parametric drawings.
But the question still remains...what is the "standard" orientation if there is
such a thing. Me thinks the manufacturers had one in mind, but haven't
promoted it that I have found.DanK

Hi Dan. (I'm trying to find a good video or text answer to your question. but
for now this is how I see it.)
When I started doing woodworking, I was taught to use a story-stick/straight
line transfer. Everything was taken form the same point/end on the stick. (X&Y
used different marking) Latter I got into drafting, again I took my
measurements form one starting point on the paper. Years (many years) latter, I
got into the machine trades and into pipefitting. These same methods/
concepts, have worked very well for me, (X is horizontal and Y is victual from
the point of reference,) Until I ran into computer controlled machinery. At
this point I had to change my line of thinking SOME , and learn some new points
of reference names, ( 0, and Z axis.)For me I still like the Straight line
transfer methods, reading numbers like .0001 (+or-. 0003) is for me a PAIN,
and gives me a headache. ( a scribe/knife edge or punch is always a better way,
then using a pencil or sharpie marker.) But who (or whom) can say which way is
right? I guess you could say, the best method is one you understand and apply
accurately. I hope this helps? (or in the very least, I don't muddy up the
water for you.) ;-)
Have a great day.

This raises a question. What is the XYZ axis orientation commonly assumed for
the legacy mills?
In metal working, the XYZ coordinate system has a floating origin based upon
the work. But the orientation is the same no matter where the origin is. My
math training orients the system so that the origin is at the left, X proceeds
to the right, Y proceeds to the back, and Z proceeds upwards, all positive
directions with negative on the other side of the origin respectively. This
led me to some confusion reading about metal lathe work. From wherever the
origin lies, usually somewhere along the centerline of the axis of workpiece
revolution, X axis proceeds in positive direction away from user (towards the
back), negative direction towards the user (front). The Y axis proceeds left
(negative) and right (positive). Thus, in metalworking, the X and Y axis
appear interchanged from the math standard. Milling operations use the math
standard.

Very interesting concept for sure. I was just looking at my woodchuck and
trying to determine how I might make a floating router attachment to follow a
template too. Will see what happens as I have many other things on the radar.
Thanks for sharing Curt and Mike thanks for the videos on your past
experiences. Kind Regards,

Hello Everyone.
Mike Pung made this video 7yrs ago.
https://www.youtube.com/watch?v=nh1JTcyLWOI X Axis Template follower.
Awesome idea, and something that Other Legacy users might want to try. (Note:
Mike is using a Wood Chuck Mill, but any Legacy mill could do the same thing,
more or less with some simple MOD's.)
Sometimes the simple things are Hard, and other times the hard things are
simple. ;-)Thanks Mike. This video is worth seeing again.
