I got one in a shop auction, 8", never out of the box. It is marked
STM and made in China. It seems fairly well built. I got it to put on
my mill/drill X-axis, but the setup eludes me. The end brackets have
holes and are pretty straight forward, but the back of the travelling
digital readout head has 2 small tapped holes. I'm not sure of the
connection here. I guess it must be attached to a bracket on the
mill/drill and the ends on the table, but it as only an 8" travel.If
the table travel is longer, I assume I must design the brackets to be
movable to encompass that extra travel. Can some kind person here give
me a few ideas on this subject or point me in the right direction, a
websight perhaps?

Avoid all that confusion. Get some duck tape and a ruler out of your kids
pencil box.

I ASSume you are describing a DRO encoder. With only 8" of travel, this
would be for either the quill or Y axis on a bridgeport style mill. The
encoder must match the travel of the axis it is mounted to, or be longer
than the travel of the axis. You cannot use it on an axis that is longer
than the encoder travel.

The ends mount solid to the machine frame. The reader mounts to the axis.
The alignment must be extremely good the full travel.

You can't 'idiot proof' anything....every time you try, they just make
better idiots.

Something like, "If I have to tell you, you probably shouldn't be using it
anyway"?
