If the rod tip should break in the cutter, it can be removed by unscrewing the brass
coupling, removing the cutter and pushing out the broken rod tip, while avoid
damaging the teeth of the cutter.
WARNING
TAKE CARE WHEN HANDLING THE CUTTER: IT IS VERY SHARP.
7.2.2
Shaping Carbon Rods for Ramped Evaporation
When shaping rods for ramped evaporation, it is necessary to produce a 1.4mm
diameter x 5mm long tip to the rod using the shaper with the red handle. Remove the
yellow protective cap by pulling the tab. To prevent accidents, replace the cap on the
unused cutter.
7.3
Fitting the Carbon Fibre Insert
Figure 7-6.
Carbon string insert
The carbon fibre insert (10455) is designed for carbon evaporation from carbon cords,
carbon fibre woven cord and carbon fibre fine strands (see
Figure 7-6
).
1.
Check the machine is not operating.
2.
Press down firmly on the top cover to release the latch.
3.
Lift the top cover and lay back against its stop.
4.
Turn the two securing buttons to release the installed insert and remove the insert.
5.
Prepare the carbon fibre insert for installation by removing from any packaging,
plastic bags etc. Check the ‘O’ ring in the outer ring of the lid assembly for
damage or debris and clean or replace as required.
6.
Place the insert in position in the outer ring of the lid assembly carefully locating
the M3 screw head in the rim of the insert in the slot to the right of the outer ring.
7.
Lock the insert in position by turning the securing buttons until their flanges
overlap the insert.
8.
Fit the carbon cord (C5421) between the two clamps. Do not pull the cord tight or
induce it to loop. For most applications, the spring-loaded clamps adequately
secure the cord and provide the correct tension. However, for controlled pulse
evaporation, you will achieve more repeatable results if you remove the springs
and tighten the clamps using the screws.
9.
If you are using fine strands of fibre (C5461 - not suitable for controlled pulse
evaporation), fold in half and gently twist together before fitting between the
clamps.
10.
To prevent excessive fraying of the cord, cut it to length (35mm) after clamping.
11.
Close the lid assembly on to the glass chamber assembly.
12.
Check the copper terminal contacts on the top of the insert are clean and free
from damage, (They must have a flat top face.) and that the contacts in the
underside of the top cover assembly are also clean and flat.
