STAGE 1 (Left Side):
- Draw a horizontal silver threaded rod (Worm 1)
- Below it, draw a gold gear wheel with 20 teeth (Wheel 1)
- Worm 1 touches Wheel 1 (they mesh)

THE CONNECTION:
- From the CENTER of Wheel 1, a gray metal shaft extends to the right
- The CENTER of another horizontal silver threaded rod (Worm 2) is attached to this shaft
- So Worm 2 is connected to the shaft coming from Wheel 1's center

STAGE 2 (Right Side):
- Below Worm 2, draw a gold gear wheel with 18 teeth (Wheel 2)
- Worm 2 touches Wheel 2 (they mesh)

LABELS:
- "20:1" near first pair
- "18:1" near second pair
- "360:1" at bottom
- Green arrow into Worm 1 (input)
- Red arrow out of Wheel 2 with dial (output)
STYLE: 3D render, isometric view, metallic surfaces, industrial design
- Worm 1 and Worm 2 are SEPARATE pieces (NOT one long rod)
- The ONLY connection is: Shaft from Wheel 1 center → Worm 2 center
- Worm 1 on LEFT, Worm 2 on RIGHT (NOT same side)
- Worm 2 does NOT touch Wheel 1
Both worms must horizontal
