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.
Cable
Spiral cable wrap for protection.
