This propane tank figure on a tricycle is more than yard art, it’s a statement piece about imagination and reuse.
Rusted pipes and fittings form expressive limbs, while a pair of old glasses and a cheeky smile give it character. The weathered finish adds authenticity, making it appear like an artifact discovered in an eccentric inventor’s workshop.
It stands as a reminder that creativity can transform the most ordinary, discarded objects into unforgettable works of art.
Materials Needed
- 1 medium propane tank (empty, cleaned, approx. 20 lb)
- 1 old children’s tricycle (preferably vintage)
- 4 scrap metal pipes (16-20” long)
- Metal washers, nuts, and bolts
- Small round scrap pieces
- Metal wire or chai
- Welding machine, grinder, and safety gear (gloves, mask, jacket)
- Rust-resistant spray sealant (optional)
Step-by-step Guide
Step 1: Prepare your propane tank by ensuring it’s completely empty and safe. Remove any valves and sand the surface lightly to eliminate flaky rust.
Step 2: Position the propane tank on top of the tricycle seat and weld it securely in place. This forms the torso of your robot figure.
Step 3: Attach the legs using metal pipes. Then weld the bottom ends near the pedals to make it appear as if the robot is pedaling. For the arms, weld pipes to the sides of the tank and connect them to the handlebars.
Step 4: Create a face by welding washers or bolts for eyes, scrap pieces for ears, and shaping a small piece of metal into a smile. Adding wire or chain hair brings even more personality.
Step 5: Make final adjustments to the pose, ensuring the robot looks balanced on the tricycle. If needed, reinforce the wheels for stability.
Step 6: Leave the sculpture with a natural rust finish for a rustic look, or apply a clear outdoor sealant to preserve it. If you prefer a cartoon-like effect, paint it with vibrant colors.
Tips:
I’ve found that leaving a little rust intact gives these sculptures more character like they’ve been riding around for years.
If you place it in a garden, let some flowers grow nearby, and it will look like your metal rider has stopped for a rest among the blooms.
