4.3.2.1
Affixing the Lateral Stop Bracket to the Mast.
For fantasy cutting,
i
t is necessary to eliminate lateral
swinging of the Yoke
– to align the Quill, and the dopped stone it holds, on the centerline of the Grinding-
Polishing tool. T
o do this, a “
Lateral Stop Bracket
” is provided – it mounts onto the Mast. Here are the
mounting steps.
Here is the
Lateral Stop Bracket that
eliminates Yoke lateral swing
–
and allows tweaking of the fixed lateral position.
The Lateral Stop Bracket
attaches to the Riser Block (the Block that rides up
and down on the Leadscrew), - a forward-extending arm of the Bracket extends
forward, making contact with the Yoke
– acting as a brake on the Yoke –
preventing lateral movement. The actual contact with the Yoke is through a
Screw (a Screw that can be used to tweak
– fine adjust - the lateral position of
the Yoke, aligning the Quill with the centerline of the position 1 Motor
The Lateral Stop Bracket
attaches to the Riser Block, held by two screws.
This picture shows the upper of the two screws being inserted
– ready to be CW
tightened. If you have an old Ultra Tec Mast, you will see those two side holes
are missing
– in which case you will see that the Bracket Plate also works as a
C-clamp gripper). Finish mounting that plate
– snug the screws. (Can the C-
clamp screws be used as backup for the two main screws? Yes, if you feel like)
