OPERATING

Recommendation: Prior to starting work, practise bevel
cuts on scrap material.
Stand to the left of the Workcentre, hold the workpiece
firmly down onto the front edge support and against the
work panel. As the back of the workpiece passes off
the front edge support, avoid dipping it down against
the blade, causing a slight step in the bevel. This is
particularly noticeable with shorter pieces due to limited
contact with the edge supports.
Having found the best hand positions to avoid the final
'dip' on small pieces, begin practising on larger pieces.
Try using either the top of the work panel, or the top of
one of the rebates in the panel, as finger rests to help
control the workpiece throughout the cut.
For additional support use the sandpaper-faced batten,
Fig.5, or the protractor, Fig.4.
Note: To achieve a perfect bevel, the workpiece must
have a perfectly straight edge to begin with.
1. Wide Workpieces (Fig.3)
The maximum manageable width of a workpiece depends
on the skill and experience of
the operator. As a general rule,
widths up to 600mm (24") can
be handled quite comfortably by
an experienced operator.
For larger workpieces, have a
second person to assist you.
2. Long Workpieces
When bevelling long workpieces, use a Triton Multi-Stand
to provide infeed and outfeed support for your workpiece.
Alternatively, have someone assist you.
3. Narrow Workpieces (Fig.4)
The Workcentre protractor, inserted into the slot along the
top of the Work Panel (A), can be used for extra guidance
and support when bevel cutting
narrow workpieces.
The protractor should slide
smoothly, without sidewards play
along the full length of the slot.
If this is not the case loosen the
Phillips-head screws and adjust
the width of the slot until the
GB
protractor slider strip fits snugly,
then re-tighten.
If necessary spray the slot with a spray lubricant, such as
RP7 or WD40, to improve the protractor sliding action.

4. Awkward Workpieces (Fig.5
& 6)
When bevelling short or awkward
shaped pieces, trim a batten
from 12mm (
") material to fit

flush within the recess running
along the work panel. Sandpaper
attached to the face of the batten
will provide grip and support for
the workpiece.
If bevelling small or awkward
pieces on a regular basis we
suggest you construct a hold-
down jig, as shown in Fig.6, for
safer more accurate guidance of
the workpiece.
5. Chamfering (Fig.7)
If you wish to chamfer an edge,
rather than cut a full bevel,
unlock the Bevel Ripping Guide
and move it to the required
Fig.3
position. Both ends must be
locked at the same selected scale
reading.
6. Fine Work (Fig.8)
To protect fragile work from
splitting near the end of the cut,
move the front edge support
closer to the blade, as shown in
Fig.8. This will provide greater infeed support. After any
adjustment, make sure the clamping screws are fully
tightened. Note: chamfers are not possible in this position.
7. Compound Mitres
Compound mitre joints require the use of a Series 2000
Workcentre protractor.
Due to the difficulty in calculating the true cutting angles
Fig.4
required for compound mitre joints, the chart opposite
covers some common joints.
For joints not shown on this chart, equations are provided
overleaf for you to calculate the various cutting angles,
using a scientific calculator.
The scales on the Bevel Ripping Guide and the protractor
are calibrated in single degree increments. While this
is suitable for general work, compound mitres require
settings within the degree increments. Carefully estimated
fractions of a degree will provide the required results.
