A man has made an out of this world item to raise money for charity - a functioning model dalek.

Andy Farley, 52, painstakingly spent many hours building a life size replica of Doctor Who's classic nemesis, which can move around at speeds up to 20 miles per hour.

Mr Farley, an engineer from Wool, now intends to give the dalek away in a raffle draw that will raise money for the Dorset and Somerset Air Ambulance service.

He based the design of his dalek on plans from the Radio Times dating back to 1973, and the model is full size. It is fitted with a petrol engine.

The dalek was given the name 'Top Fuel Dalek 478', referencing the number of hours Mr Farley put into its construction.

Mr Farley said that the winner would need large storage space for the dalek, and also estimated that the parts would sell for hundreds of pounds if they did not want to keep it.

He has put the dalek on display at Huntspill in Somerset and at the Kickback Show in Cheltenham to promote the raffle, and is hoping to display it at the Royal Bath and West Show.

He intends to continue to display it at various events until the close of the raffle on November 1, 2020.

Other projects Mr Farley has undertaken in the past include a Crapazaki 500cc site toilet, which was sold for cancer research, and a Honda GD90 V Twin diesel Motorbike 479cc.

He said that he chose to fundraise for the air ambulance service this time because he believes it is underfunded.

Daleks are the long-time enemy of the title character in the popular BBC science fiction show Doctor Who, and have been featured on the show many times over its more than 50 year run.

They were created by Terry Nation, and first appeared on television in 1963.
