How to Draw Pulley — Free Practice Sheets

Drawing a pulley is a useful exercise in combining curved mechanical shapes with clear structural details. This page guides you through the key features: a grooved wheel with concentric lines, a teardrop-shaped side plate with two small holes, a connecting ring at the bottom, and a rope loop hanging below. You will trace a reference outline first, then practise the contour on your own. Because drawings can vary, you will assess your work by visible features and proportions rather than exact matching.

Start with the side plate and mounting holes

The pulley's main body is a teardrop-shaped side plate. Begin by drawing a rounded top that tapers to a narrower bottom. This shape gives the pulley its characteristic profile. Inside the plate, add two small circular holes. These represent mounting or rivet points and help anchor the drawing's structure. Keep the holes roughly equal in size and place them where the plate is widest, usually near the top and middle. The tapered bottom should remain clear for the connecting ring.

1. Draw a teardrop outline: a rounded top that gradually narrows to a tapered bottom.
2. Add two small circles inside the plate for mounting or rivet points.
3. Check that the holes are similar in size and sit within the wider part of the plate.

Add the grooved wheel with concentric curves

Attach the grooved wheel to the left side of the side plate. The wheel is shown as a set of nested curved lines, not a single circle. These concentric curves indicate the rope groove and the wheel's thickness. Start with the outermost curve, then add one or two inner curves that follow the same shape. The curves should meet the plate cleanly, as if the wheel is mounted on an axle. Keep the spacing between curves even to suggest a consistent groove.

1. Draw the outermost curve of the wheel on the left side of the plate.
2. Add one or two inner curves that follow the same arc, showing the groove.
3. Ensure the curves connect to the plate without gaps or overlaps.

Finish with the connecting ring and rope loop

At the bottom tip of the teardrop plate, draw a small connecting ring or shackle. This links the pulley body to the rope. Then draw the rope loop as an elongated oval hanging from the ring. Add an inner line inside the oval to show the rope's thickness. The loop should hang straight down and remain proportional to the pulley. Avoid making the loop too wide or too narrow; it should look like a continuous rope passing through the ring.

1. Draw a small ring or shackle at the tapered bottom of the plate.
2. From the ring, draw an elongated oval for the rope loop.
3. Add an inner line inside the oval to indicate rope thickness.
4. Check that the loop hangs vertically and is proportionate to the pulley.

Practise with tracing, grids, and partial outlines

Use the practice sheets to build accuracy. First, trace the reference outline to learn the contour. Then, try drawing the pulley independently and compare your result with the separate full reference sheet. Other sheets offer a blank grid for copying by matching intersections, a bounding frame with a center guide for placing the silhouette, and a partial outline where you complete the missing right-hand portion. Each method targets a different skill: contour memory, proportional placement, and completing a structure from partial information.

1. Trace the reference outline to familiarise yourself with the shape.
2. Draw the pulley independently and compare with the full reference sheet.
3. Use the grid sheet to copy the pulley by matching grid intersections.
4. Use the bounding frame and center guide to place the silhouette before adding details.
5. Complete the blank right-hand portion using the full reference as a guide.

Check your work

• The side plate is teardrop-shaped with a rounded top and a tapered bottom.
• Two small circular holes are present inside the side plate.
• The grooved wheel is drawn with nested concentric curves on the left side of the plate.
• A small connecting ring or shackle is drawn at the bottom tip of the plate.
• The rope loop is an elongated oval hanging from the ring, with an inner line showing thickness.
• The overall proportions are plausible: the wheel, plate, and loop relate sensibly in size.

Worked example

pulley: Trace the reference outline, then practise the contour independently. Compare with the separate full reference sheet.

Common mistakes

• Drawing the grooved wheel as a single circle instead of nested curves. Add one or two inner curves that follow the outer arc to show the rope groove and wheel thickness.
• Making the teardrop plate too round or too pointed at the bottom. Aim for a rounded top that tapers gradually to a narrow but not sharp bottom tip.
• Placing the rope loop off-center or making it disproportionately large. Hang the loop directly below the connecting ring and keep its width roughly one-third of the plate's widest part.
