¼-20 tapped mounting holes on the back of the carriage & the lathe bed (not shown).

10-32 & 1 (top, center) ¼-20 tapped mounting block.

L-channel mounted to block to hold & protect the scale from impact/debris.

A very sturdy structure.

Six-inch, vertical style scale mounted to L-channel; same scale style as the mill Y & Z scales.
I soldered a 100µF 10v tantalum capacitor across the battery leads of the scale.

6-32 drilled & tapped (50% threads for steel) in the cross slide table end.
This particular tap handle has a guide that mounts into the drill press chuck.

Measured scale run out & shimmed as necessary. The reach of the 2" dial helped.

Brackets & connector rods (6-32 screws) shown for the X & Z1 axes scales.
The single pivot points of the connecting rods allow easier alignment & the
round rods do not snag debris as easily as flat surfaces.  Since the scale end
brackets are slotted, the vertical adjustment was easily achieved
by moving the scale to one end, tightening the mount nut then
moving to the other end & tightening the nut. The wires hang
off the bracket end which keeps them free to move with the carriage.
SPC cables from LMS. All cable plugs are held in place with a spot of hot glue.

Cross slide fully retracted showing how all the brackets clear each other.

I have installed rubber washers on all the scale mounts to
allow a little floating to reduce the strain on the transducers.
