4.2 THE TABLING ADAPTER.
Used to work on the table of the gem, it points the dopped gem straight down
at the lap (it's often called a "45
Adapter", since, when it is used, the axial angle is set at 45
).
To assemble the Tabling Adapter to the Quill, turn in the Retention Set
Screw so that
there is no extension of it above the Quill’s outer surface.
Then slip the Tabling Adapter onto the Spindle, until it stops. Slightly
snug the set screws which hold it to the Spindle.
Alignment of the Tabling Adapter: Set the axial angle at 45
. Bring the
bottom surface of the Tabling Adapter down onto the lap surface, and
when it is flat from side to side, lock the set screws.
4.2.1 Tabling
—some accessory choices.
You may wish to purchase a Tabling Aligner (shown on the left), an accessory
for fast accurate alignment of the Tabling Adapter. The Tabling Aligner fits
directly to the hole that holds the dop
— eliminating several tolerance errors,
and provides good “feel” of the flush setting onto the lap surface
4.3 THE TRANSFER FIXTURE.
The Transfer Fixture (part
of the Kit that comes with your machine) is machined from
one piece, assuring its stability and accuracy. The ends of
the Transfer Fixture are matched "V-Blocks", mirror images
of each other--so there's no rule for which side to put the
original dop or the new (receiving) dop. Use whatever feels
comfortable. Also, the Transfer Fixture can be set on end,
with the V's vertical--something you may find useful.
On each V-Block, there is a clamp for holding the dop in position in the V (or, with light tightening, allowing a
dop to slide in the V), and a pusher that aligns the key at the end of the dop and pushes the dops together.
Brackets that bridge over the pushers have nylon-tipped set screws that bring pressure on the pusher, keeping
it in its track, as it slides.
When the clamps are loosened, they can be turned sideways, getting them out of the way for easy insertion or
removal of dops. The chamfer of the keyed dop can face up or down in lining up against the pusher.
