This DRO
modification has been removed for the
CNC conversion
but the information has been retained for reference.
Scale & Brackets
Simple L-bracket used for linkage.
Drilled &
tapped the column for
10-32 button-head screws.
Detail of the older style SPC socket on a horizontal
scale (manual). The newer models have an
improved (enclosed) receptacle.
Cable
Rubber washers on the scale linkages allow a little
floating to reduce the strain on the transducers.
The
RF-25 mill's free-floating
Z-axis design works
so well that now all of my mill & lathe scales
are attached at only one end while the other end
remains captured but loosened
to allow floating.
This approach greatly reduces minor out of alignment
induced stress on the
transducer. This
design also helps to reduce DRO jitter as does a clean,
deburred transducer
with NR capacitors.
Spiral cable wrap for protection.
