This DRO modification has been removed for the
CNC conversion but the information has been
retained for reference.

Carriage Modification

The right side of the Taig's cast
aluminum carriage was fly cut, flat.

Holes were tapped with 75% (Al) 6-32
threads to hold the Y-axis L-bracket.

Tapped the Taig steel base with 50% (Fe)
6-32 threads for the lower scale bracket.

Scale Brackets

Y-axis upper bracket for the 6" scale.
The SPC socket faces down.

The bracket top is too deep to
clear the table crank.

The top of the Y-axis bracket must allow the X table
handle & bearing plate to completely clear.

The L-channel serves as the scale's mount &
protects it from impact, fluid & debris.

Rubber washers on all the scale mounts allow a
little floating to reduce the strain on the transducers.

Used self-aligning, spherical washers
to allow easy lower bracket assembly.

Spherical (L) & rubber washers (R) installed.

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.
