In Bentley Motor's wood shop, typical car production line sights, smells and sounds – machines, heat, buzzers and perhaps a whiff of oil – are supplanted by the sweet scent of exotic woods such as walnut, cherry and eucalyptus and a hushed ambience akin to a library.

Phil Gent is technical manager in Bentley’s wood shop and an expert in using the material in car production.

“Veneer is one of our key materials. It comes from a tree’s root ball underground,” he explains. “Our veneer supplier will dig it up, and soak it in a vat of chemicals and water for a number of days. It is then put on a circular lathe and the veneer is peeled off the root ball. The veneer comes off in random sizes. When we get it, it is sold in packs of 24 sheets.

“We use the root ball because that’s where the most decorative bit of the veneer is. So the older the tree is, the better for us. With young trees, you don’t get a lot of decoration and obviously you get less pieces of veneer because the root ball is smaller.

“Out of all the veneer produced in the world, we estimate that we’re selecting from the top five or ten per cent. There’s a lot of time, effort and money spend ensuring that the customer gets the best. When our storeroom is full we could have up to £250,000 worth of veneer in there.”
