Multimeter Box
Tasmanian Oak, red cedar, jarrah
260 x 158 x 76mm
The cardboard
box containing my multimeter started falling
apart and although I had thought to make
a replacement, it was not until I read
about the competition that I decided to
give thought to the design and constructions.
I noticed drill cases were designed so
the drills sit up when opened –
the desired feature for my box. Transferring
this design concept from small, slimline
cases made of plastic to a strong wooden
box using relatively thick material provided
an interesting exercise in geometry, trigonometry
and drawing to end up with a box which
sat at the correct angle and was neither
bulky nor proportionally unattractive.
The result was a box with overall dimensions
of 260mm long x 158mm wide x 76mm high
and when opened fully the body sits at
65 degree to the horizontal.
I used Tasmanian oak, red cedar and jarrah.
The lid pivots are 6mm hardwood dowels
turning in bushes of nylon pneumatic tube.
Brass cylinder hinges and box catch provide
the hardware. All timber is recycled or
off cuts: Tasmanian oak for the lid and
base from an old 19mm thick shelf re-sawn,
dressed to 12mm and 6mm respectively;
sides and partitioning from an off cut
re-sawn and dressed to 6mm. The cedar
for the corners was scrap and the jarrah
from an old fence picket.
With the exception of the finger jointed
corner posts, construction was a straight
forward pin and glue operation. The pins,
used to provide extra strength in holding
the base, are small tacks with heads cut
off and pressed in with Superjaws at final
assembly. The partitions are glued only.
Triton yellow glue was used throughout.
The joints were constructed using the
Triton Finger Jointer. The 12mm square
corner post stock was sawn so that the
grain ran across the diagonal. This resulted
in grain oriented with the sides but at
45 degree across the corner such as a
spline in a splined mitre. To rout the
corner posts the movable fence of the
jig was replaced with a hand held low
fence for safer handling and to prevent
chipping.
The box was smoothed with 600 grit paper,
given a coat of gum oil and a finishing
coat of neutral Black Bison Wax and given
a green felt lining.
