Select the required template
This machine is supplied with a standard template with
numerals and an English alphabet. Using the upper side, letters
up to 1.3 mm in height can be engraved while with the reverse
side the engraved letters can be up to 0.8 mm in height. Before
engraving, select a suitable size and style of letter.
Holding the ring
Insert the ring (N) into the grooves of the three self-centring
fibre jaws (E) and tighten by turning the knob (C) clockwise to
rotate the chuck disk (H) as shown in Fig. 2. The jaws have
narrow and wide grooves for different sizes of rings. Reverse
the jaws when necessary by loosening the locking nut (D) as
illustrated in Fig. 3. When engraving the inside of a ring with a
stone, place the stone between the two jaws with the largest
spacing.
Engraving rings
1. Before engraving, decide on the starting position of the first
character according to the stone, carat mark, etc. on the
ring (N). To do so, rotate the ring in the fibre jaws (E) by
raising the lever (F) as far as the stop of the adjusting screw
(R). The lever is shown in Fig. 1 and Fig. 4 (F).
2. The template (J) is released by pushing forward the release
lever (I) as illustrated in Fig. 1 and Fig. 5. Turn the dial
either clockwise or counter clockwise with your left hand
and lock the first character to be printed on the dial in front
of the stopping pin (B) see Fig. 6. Push down the lever (F)
to bring the diamond cutter (O) into contact with the inside
of the ring and press down on the stylus cap (L). Once this
is done, trace the grooves of the character on the template
with the tip of the stylus (M) as shown in Fig. 6.
3. To achieve a neater result, trace the letters with the tracing
stylus (M) as shown in Fig. 7 and Fig. 8 rather than as
shown in Fig. 9.
4. After tracing one letter, raise the lever (F) until the stop of
the adjusting screw (R) hits the baseplate and gently
release. The ring in the ring chuck (H) turns and the space
between the characters will automatically be set. At the
