- Clean the blade edge regularly with a dry cloth to remove graphite or ink smudges that could transfer to your drawings.
- Handle with care to avoid nicks or dents along the straight edge, which are crucial for precise lines.
Triangles: Typically coming in 30-60-90 and 45-45-90 degree sets, triangles are used to draw accurate angles and vertical lines when used with a T-square.
- Care Tips:
- Like T-squares, store triangles flat to prevent warping.
- Clean edges to ensure smooth, smudge-free lines. Isopropyl alcohol can be used for stubborn marks, but ensure it’s fully dry before use.
- Check for chips or cracks, especially at the corners, which can affect accuracy and should be addressed or the triangle replaced.
Triangular Scale: This ruler features multiple scales on each face, allowing for drawings to be made at various proportions.
- Care Tips:
- Store scales in a case or drawer to protect the edges and markings from damage.
- Clean gently with a soft, dry cloth. Avoid abrasive cleaners that could remove the scale markings.
- Handle carefully to prevent drops that could damage the edges or corners, affecting measurement accuracy.
Compass: Used to draw circles and arcs of varying radii.
- Care Tips:
- Keep the points sharp for clean, precise circles. Use a compass sharpener or fine sandpaper to maintain sharpness.
- Ensure the hinge is properly tightened to prevent slippage and maintain the desired radius while drawing.
- Store in a case to protect the points and prevent damage to other tools.
Divider: Similar to a compass but with points on both ends, dividers are used for transferring measurements and dividing lines or spaces into equal segments.
- Care Tips:
- Maintain sharp points for accuracy, similar to compass care.
- Check hinge tightness regularly to prevent unwanted changes in measurement.
- Store in a case to protect the points. Consider using point protectors if available.
Protractor: A semicircular tool used to measure and lay out angles.
- Care Tips:
- Handle with care to avoid scratching the clear plastic, which can make readings difficult.
- Clean with a soft cloth. If needed, use a mild plastic cleaner, ensuring it doesn’t cloud the material.
- Store flat to prevent bending or warping, which can affect angle accuracy.
French Curve: A template with various curves used as a guide for drawing smooth, non-circular curves.
- Care Tips:
- Store flat to prevent warping and maintain the integrity of the curves.
- Clean edges to ensure smooth lines. Remove any pencil or ink buildup with a soft cloth or plastic-safe cleaner.
- Protect from scratches and nicks to preserve the smooth curves that are essential for accurate drawing.
Erasing Shield: A thin metal or plastic sheet with openings of various shapes, used to protect specific areas of a drawing while erasing nearby lines.
- Care Tips:
- Keep clean and free of eraser debris. Wipe with a soft cloth.
- Store flat to prevent bending, which could make it difficult to use accurately against the drawing surface.
- Handle carefully to avoid bending or damaging the delicate openings.
Pencil Sharpener: Essential for maintaining sharp pencil points.
- Care Tips:
- Regularly empty shavings to prevent the sharpener from becoming clogged.
- For manual sharpeners, ensure the blade is sharp. Replace blades when they become dull for clean sharpening and to prevent pencil lead breakage.
- For electric sharpeners, follow manufacturer’s instructions for cleaning and maintenance.
Sandpaper Pad: Used to refine pencil points, creating conical or long points without breaking the lead.
- Care Tips:
- Replace sandpaper sheets as they wear out to maintain effectiveness.
- Keep free of excessive graphite buildup by tapping it gently after use.
- Store in a dry place to prevent moisture damage to the sandpaper.
Pencils: Drafting pencils come in various lead hardnesses to produce different line weights and shades.
- Care Tips:
- Store pencils in a case or tray to prevent lead breakage.
- Sharpen regularly using a quality sharpener or sandpaper pad for consistent line quality.
- Avoid applying excessive pressure when drawing to prevent lead breakage and damage to paper.
Drafting Paper: A high-quality, thick paper designed for drafting, available in sheets or rolls.
- Care Tips:
- Store paper flat in a drawer or portfolio to prevent creases and wrinkles.
- Keep paper in a dry environment to prevent moisture damage and warping.
- Handle with clean hands to avoid transferring oils or dirt to the drawing surface.
Eraser: Used to remove pencil lines and marks. Different types are available, including kneaded, rubber, and vinyl erasers.
- Care Tips:
- Keep erasers clean to prevent smudging. Rub rubber or vinyl erasers on a clean surface to remove graphite buildup. Kneaded erasers can be cleaned by stretching and kneading them.
- Store erasers in a clean, dry place, away from dust and debris.
- Replace erasers when they become hard or excessively dirty, as they may start to smudge rather than erase effectively.
Drafting Tape: Low-tack tape used to secure drafting paper to the table without damaging the paper upon removal.
- Care Tips:
- Store drafting tape in a cool, dry place to prevent the adhesive from drying out or becoming too sticky.
- Keep the roll clean and free of dust or debris that could reduce its adhesive quality.
- When applying, use only enough tape to secure the paper; excessive tape can be harder to remove and might still risk tearing the paper.
General Tips for Drafting Tool Maintenance
Beyond specific tool care, several general practices will help maintain your entire drafting toolkit:
-
Handle with Care: Avoid dropping tools, as this can damage points, edges, and overall accuracy. Treat your drafting tools with the same respect you would any precision instrument.
-
Dedicated Cutting Tools: Never use measuring tools like scales or triangles for cutting paper or other materials. Use a dedicated utility knife or scissors to protect the edges of your measuring instruments.
-
Regular Cleaning: Wipe down the surfaces and edges of your triangles, T-squares, and other tools regularly. This prevents graphite and dirt buildup, ensuring clean lines and preventing smudging.
-
Pencil Point Discipline: Sharpen pencils before each drafting session and store them properly afterward. A sharp pencil is crucial for precise work, and proper storage protects the points from damage.
-
Organized Storage: Invest in or create an organizer for your drafting tools. Hanging measuring tools or storing them in individual compartments prevents scratching and damage.
-
Separate Containers: Keep drawing tools separate from erasing tools and accessories. This prevents eraser dust from contaminating drawing tools and keeps your workspace cleaner.
-
Protect Your Paper: Store drafting paper in plastic tubes or portfolios to shield it from dust, dirt, and moisture. This ensures your paper is always ready for use and free from imperfections.
-
Personal Toolkit: Avoid lending or borrowing drafting tools whenever possible. This minimizes the risk of damage, loss, and keeps your tools in the condition you maintain them.
By implementing these care and maintenance practices, you will not only prolong the life of your drafting tools but also ensure they consistently deliver the precision and reliability needed for your best work. Taking good care of your drafting tools is an investment in the quality and accuracy of your designs and drawings.
