How It's Made

This programme examines how manufacturing processes have been developed for cast‑iron stoves, ultralight aircraft, snow groomers and rubber bands, from traditional casting to modern composites. It explores the techniques, materials and innovations that shape production across these diverse products and improves efficiency.

The programme titled Cast Iron Stoves/Ultralight Aircraft/Snow Groomers/Rubber Bands offers a look at how various manufacturing processes have been created and refined. It treats each of the four subjects as a separate case study, showing the steps that have led to the modern ways these items are produced. In each episode the focus turns to the evolution of the techniques used to make the product. Viewers see how cast‑iron stoves were once forged and how those methods have been altered over time, the ways lightweight structures are assembled for ultralight aircraft, the specialised tooling required to build snow‑grooming machines, and the simple but effective procedures that turn rubber into elastic bands. The series walks through the engineering challenges that each industry faced, illustrating how solutions were found and how the processes have been streamlined. By breaking down the production stages, it highlights the practical problem‑solving that underpins everything from household heating to recreational equipment. Overall, the programme provides a concise overview of the craft behind these diverse objects, revealing the common ingenuity that links the making of a cast‑iron stove to the construction of an ultralight aircraft, a snow groomer and a rubber band.
