I needed to add this readout as it is impossible to get any sort of repeatability
using the Fine Quill Feed. Started out making fancy brackets and shafts to
go in place of the depth stop rod then decided to try this simple method.
The readout is screwed from behind, directly onto the thin control panel.
Drilled and tapped a hole in the Quill bracket that connects to the depth stop rod
and attached a thin piece of sheet alluminium to the bottom bracket of the scale rod.
It works very well and has made the machine usable at last.
