Carriage Modification

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

Holes are tapped with 6-32 threads to hold the Y-axis L-bracket.

Tapped the Taig steel base with 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 mount & protects it from impact, fluid & debris.

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

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

Rubber washers 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, de-burred transducer with NR capacitors.

Cable

Spiral cable wrap for protection.
