Chapter 11: Artifact Drawing 301
for any type of drawing. From personal experience, it is amazing how often departmental or group equipment is either missing, broken, or unusable when it is needed for a vital, rushed job, whereas with one’s own equipment there is only one person that can be blamed if it is not there. In general, you know exactly what you have, and that it is all in one place. But beware, there will be constant harassment by people wanting to borrow pens that are always in working order. The following is what the author keeps in a drawing box:
• A3 drawing board with parallel rule, rotating head; in this case, a Rotring Rapid, but others are just as good and some possibly cheaper
• 50 sheets of pre-cut A3 drawing film and some A3 metric graph paper
• 1 set of 9 drawing pens 0.13–2.0mm, Rotring Sec-o-mat Isograph
“F” pens
• Compass set, small circles, large circles, and compass beam radii up to
about 250mm
• 500-mm stainless steel flat ruler
• 10-m retractable tape measure
• Circular protractor, diameter 300 mm
• Set of large calipers, 500-mm jaws
• Set square
• Vernier calipers, 250 mm
• Vernier depth gauge, 250 mm
• Programmable calculator
• Set of scalpel blades and blade holders, emery board for sharpening
blades, and some backed razor blades
• Scale rules (1:2, 1:4, 1:2.5, 1:5, 1:7.5)
• Set of stencils for Isograph pens
• Fine-point pencils and leads (0.2 and 0.5 mm)
• Felt-tipped pens, various colors, tip shapes, and sizes
• Rubbers, ordinary for ink on film and rod rubbers and holders
• Various inks
• Profile devices
• Blue Tac and sticking tape
• Scissors
• Paint brushes
• Proportional dividers and standard dividers
• Measuring devices
The small retractable steel tape is one of the most useful measuring devices. It is compact, flexible, and ideal for measuring large objects (about 10 m maximum). Scale rules are used for drawing, particularly for working plans at fixed scales like 1:2, 1:4, 1:5, 1:10, 1:20, and 1:100. These,
