| The
workshop rod is a full size drawing produced by the setter out.
It accurately shows the cross sections, lengths, widths and
thickness of the finished work. This
is then used to produce the Master Pattern for a production run.
Jobs may be laid out on the rod to check dimensions, angles,
etc. Jobs with raked
joints are nearly always taken-off a rod to provide the necessary
accuracy
In the case of doors
and windows that are in single plane, vertical and horizontal sections
are all that is required. Front
elevations are not normally shown unless there is a complex geometric
shape to show.
Joints are not normally
shown unless the designer or architect has specified in the drawing or
specification. They are
usually left to the good judgement of the joiner to use the correct
joint for the material, end use and aesthetics from experience and
knowledge.
Included on the rods so
that they can be referred to the contract and for later use are:
·
Rod number or Job number and a brief title that describes the
job.
·
The Contract Number and date and perhaps the client.
·
The Cutting List Number and date so that the timber can be
called up.
·
A Schedule or Range Drawing number that the job relates.
And to summarise
the other details are:
·
Accurate representation of width, depth and height of job.
·
Timber sizes, cross section, etc. exactly as finished.
Finally it should be
noted that dimensions are only written on the rod to avoid any
possibility of confusion.
The technical details
are obtained from the scaled Drawing and Specifications.
The Rod is prepared on
thin ply or hardboard usually painted with a mat white paint or
emulsion to aid vision and perhaps hide over previous drawings.
The joiner must show good
judgement in making rods especially leaving enough material for the
‘Horns’ on window frames for building-in. The horns
are usually 50 - 75 mm and also protect the frame and especially
doors, in transit.
