REF. M/PB01
Thank you for purchasing this Trend Perfect Butt™.
The following symbols are used throughout these instructions:
Denotes risk of personal injury, loss of life or damage to the
tool in case of non-observance of the instructions.
INTENDED USE
This accessory is intended to be used to scribe in work surfaces
flooring or shelves to match uneven walls. It includes four wheel
sizes to allow for different situations. The end cap can also be
used to mark the worktop offset when using Trend worktop jigs.
SAFETY
Please read and understand the safety points at the end of this
instruction as well as the powertool instructions before use.
INTRODUCTION
The Perfect Butt™ was designed to overcome a problem
frequently encountered by tradesmen and enthusiasts alike when
scribing in work surfaces, flooring or shelves to match uneven
walls. Instead of using a scrap of wood with a pencil jammed into
a hastily drilled hole, this innovative tool takes the guess work out
of what used to be a hit and miss chore. The pencil simply
remains in the centre of any of the four tracing wheels allowing an
accurate profile to be easily drawn every time.
Tip: Before committing yourself to cutting an expensive worktop or
some other material, practice profile marking and cutting on scrap
material such as cardboard, plywood or MDF offcuts. This will
ensure that you develop the correct technique and build
confidence.

OPERATION
Basic Scribing Procedure
Single Plane Profile
This example is for fitting a kitchen worktop flush up to any wall
with an irregular profile. The principles behind this process
apply to any single plane profile such as fitting a shelf or when
fixing two workpieces together.
Initial Alignment
Rest the worktop on the cabinet carcasses and position it up
against the wall ensuring that the front edge is parallel to the
front of the kitchen cabinets. Locate and measure the largest
gap between the wall and the worktop rear edge. Select the
Perfect Butt™ wheel whose radius is just greater than the width
of the gap (i.e. when the edge of the wheel is pressed against
the wall, the pencil point will still mark the work surface).
Note: Smaller wheels give greater detail when profiling
complex surfaces.

Scribing the Butt Profile
Ensure the worktop is secure and does not move. Fit the
chosen wheel to the pencil shaft assembly. Starting at
whichever end of the worktop you prefer, press the Perfect
Butt™ wheel flat onto the worktop with the edge of the wheel
touching the wall. This will ensure an accurate transfer of the
wall profile to the worktop. Hold the knurled shaft near the
base and run the wheel along the wall for the entire length of
the worktop. The internal spring in the handle will keep the
pencil in gentle contact with the surface while the wheel is
traversed.
Note: Your pencil line may not show on some laminated
surfaces. We suggest you apply a strip of masking tape
where the pencil will run. This will also help avoid
chipping the surface when the worktop is cut.

Examine the scribed line. If this indicates that too much
material will be cut off, then reposition the workpiece away from
the wall by an appropriate distance and re-scribe as required.

Cutting the Worktop
The wall profile has now been transferred to the worktop.
When cutting the worktop, always cut to the waste material side
of the scribed line. This will ensure you do not cut into the
good side of the worktop and there will be minimum material to
remove for final hand-fitting. If you have previously practiced
this technique on scrap material and you have cut accurately to
the scribed line, the final fit should be acceptable first time.

Profiling and Fitting on Two Planes
Fitting a Kitchen Worktop into a Corner with Two
Irregular Walls
If both the walls are distorted or untrue then a template will be
required to copy both wall profiles simultaneously onto the
worktop.
Process Overview
■ Place the worktop on the kitchen cabinets as near to its final
desired position as possible with the front edge correctly
aligned.
■ Rough cut a template (cardboard etc.) to cover the area
where you wish to fit the worktop.
■ Align the template and scribe both wall profiles onto the
template using the Perfect Butt™
■ Cut out the template along the scribed lines. When the
Perfect Butt™ is then run along the outer-edge of this
template, the wall profiles will be reproduced onto the
worktop with a scribing line. The worktop may then be cut
and the edge finished to carefully match the scribe line
indicated by the Perfect Butt™. The worktop will now fit
both irregular and wall profiles and can be fixed in position.
Selecting Template Material
Many materials can be used as a template as long as they are
greater than 2mm in thickness with an edge that will not
compress when it is used to trace against with the Perfect
Butt™ wheel. Suitable materials include thick card, packing
cardboard, MDF, plywood, hardboard and polyfoam.
Step-By-Step Guide
Worktop Alignment with a Known Datum
Rest the worktop on the kitchen cabinets and position it into the
corner where it is to be fitted. Ensure that the worktop is
parallel to the front edge of the kitchen cabinets - a known
datum - and that both the back and side edges touch their
respective walls.

Rough Cut the Template
The template will need to be as wide and deep as the worktop
you wish to fit. It may need to be even wider and deeper to
cover gaps, depending on the degree of irregularity in both wall
profiles. You may join multiple pieces of suitable material
together to create larger templates where necessary, but when
doing this ensure that the final template assembly is sufficiently
rigid or has assembly marks so that the pieces can be
accurately re-aligned if disturbed. The idea is to end up with a
rough-cut template that follows the existing wall profile to within
a 25mm (1”). This gap can be spanned by the smallest wheel.
Marking the Datum on the Template
Once you have your rough-cut template you must ensure that it
can record the profile accurately. Mark each side of the
template where it intersects with the front edge of the worktop.
As you have already aligned the worktop parallel to the kitchen
cabinets, these two edge marks now provide the template with
a fixed reference line to the datum, a known straight edge.
Mark a line between these edge marks and cut the template
along this line to give the template its datum line.

Scribing the Wall Profile onto the Template
With the template rough-cut to within 25mm (1”) from the walls
you wish to profile, and correctly aligned with the datum
(template and worktop aligned) you are ready to scribe a profile
onto the template. You
may wish to tape or clamp
the template in place so
that its alignment with the
datum is fixed.
