A man who has built a Dalek out of junk says he hopes Doctor Who will create a new generation of fans of the aliens.
Christopher Grylls, 11, can 'walk' Dewi the Dalek around the garden
Steel plant engineer Stephen Grylls, 46, has spent three years crafting the mechanical monster he calls Dewi.
He and son Christopher are looking forward to the return of the Daleks to Dr Who on Saturday night.
Mr Grylls, from Llandybie in south west Wales, said: "I'm not one of these Doctor Who fanatics - I just happen to like Daleks."
He has still to finish Dewi's head, but the Dalek is complete enough for Christopher, 11, to sit inside and push along the garden path with his feet.
Mr Grylls, an electrical engineer at the Corus steel plant in Port Talbot, said the most expensive part he had bought was the sink plunger used for an arm.
The rest of Dewi has been put together from scraps and leftover materials.
A toilet ballcock is the joint for the Dalek's exterminator arm, which can also be controlled from inside.
Mr Grylls hand-made the mould for the more than 50 spheres on Dewi's grey and black body.
He said: "I have scratch-built everything. It's quite satisfying to see it coming along.
A new look Dalek, which has improved weaponry
"I wanted to put in the lounge but my wife does not share my enthusiasm, so it's destined to stay in the garage."
Daleks have been able to negotiate stairs since 1988 when they first levitated towards Sylvester McCoy, the seventh Dr Who.
The new, improved 2005 version of the Daleks is now able to move its head and torso separately, so its enemies cannot sneak up on it.
Their trademark "sink plunger" weapons also have new functions, to be revealed during Saturday's episode.
Mr Grylls said he hopes the new Doctor Who show will win the Daleks the hearts and minds of younger fans.
He said: "I was scared of the Daleks when I was a child. With all the technology today, youngsters don't tend to be as scared as I was then.
"Christopher knows what Daleks are because he has seen the videos of the old films, but when his friends have come down and he has shown the Dalek to them, it has meant nothing to them."
He said he was pleased that, from what he had seen of the new Daleks, they had been "taken on to another design level".
The Daleks return to Doctor Who at 1900 BST on Saturday on BBC1.
