How It's Made

The programme examines the manufacturing processes behind customised knee replacements, the production of leaf springs, and the extraction of lavender oil. It follows each item from raw material through to the finished product, highlighting the techniques and materials used in these specialised crafts.

The programme titled Knee Replacements/Leaf Springs/Lavender Oil is presented as a single episode that falls under the broader category of a “programme”. Its format is straightforward – it offers viewers a focused look at the way three very different items are produced, from a medical implant to an automotive component and a botanical extract. In the heart of the episode the audience is taken through the making of customised knee replacements, the construction of leaf springs and the extraction of lavender oil. Each segment concentrates on the step‑by‑step process involved, showing how these products move from raw material to finished good. The approach is consistent throughout, giving a clear picture of the techniques used in each field without straying into unrelated territory. The episode’s structure ties the three topics together, presenting them side by side so that viewers can appreciate the variety of manufacturing methods on display. By keeping the focus on how each item is crafted, the programme delivers a concise yet informative guide to the creation of bespoke medical devices, essential vehicle parts and natural essential oils, all within a single, easy‑to‑follow format.
