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


Drilled & tapped two, 6-32 holes for cap head screws at the left & right front corners of the table
 to mount the X-axis scale bracket. Milled down 1-1/2" x 1-1/2" x 1/8" aluminum L-channel for the bracket.

Needed to retain the table lock feature. Shortened the hard stop 3/8" dowel pin &
tapped it to accept a 10-32 center transfer. The pin corner is smoothly rounded to facilitate assembly.

Bottom adapter plate for the X-axis scale. Note the transfer scribe line & set-screw hole.
The hole was reamed to 3/8".

Scale Mount

The unit is bolted together using self-aligning, spherical washer (pairs) between the scale & L-channel bracket.

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 floating to reduce 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.

Cable Route

The hot-glued signal cable exits to the left, is spiral wrapped & is held down by a
3/8" plastic clamp fastened down by the left, way cover cap-head screw.
