The semi-final finds the final four woodworkers getting tipsy and glamorous with drinks cabinets inspired by a specific decade. They have to craft sliding doors and complicated mechanisms in a bid to make it through to the final. However, judges Alex de Rijke and Helen Welch aren't letting up, as they set a steamy surprise challenge that may bend the woodworkers out of shape.
