of the Mechonoids, Cusick was inspired by the designs of Richard Buckminster Fuller; the expensive models, which used three two-part fibreglass casings, were made by Shawcraft Models and completed in March 1965. Like the Daleks, they were designed to be controlled by a hidden operator inside the casing. Hartnell disliked the need to be precise with his movements around the props. The Mechonoids were too large to maintain after production; a Fungoid and the Mire Beast were kept, later appearing in a display at an exhibition in 1967. With production approaching, the crew noted that it needed to use the two Dalek props on loan to Belle Vue Zoo by early March. They also enquired into loaning the two Daleks given to the Dr. Barnardo's home in Ilford, Essex; when Dr. Barnardo's indicated that the props could only be used for a few days at the end of April, the crew decided to proceed without them. Other Dalek props were sourced from Ealing Studios, and from original manufacturer Shawcraft Models in Uxbridge; at the time, another prop was on loan to a different BBC production, thought to be an episode of Hugh and I, "Bun Fight", which aired on 11 April 1965. Four of the Daleks owned by the BBC were refurbished, costing ; of this, the Publicity Department, which had been using the props extensively for promotional purposes, paid . Cusick disliked the modifications made on the Dalek casings by Spencer Chapman on The Dalek Invasion of Earth; Cusick redesigned the casings, removing the fenders and power dishes and adding shoulder slats to the midriff section. The black Dalek Supreme from The Dalek Invasion of Earth was painted silver for The Chase. Cusick also designed a lightweight prop, referred to as a "hover Dalek", which could appear to move rapidly over the sands; it was operated by Gerald Taylor. For the final shot of the first episode, Cusick and his team buried a Dalek in the sand and attached it to a Land Rover vehicle via rope; however, the casing did not rise through the sand, forcing the team to reconsider the effect. Cusick and Shawcraft Models ultimately built an 18-inch Dalek puppet operated from underneath. Cusick designed the Dalek's control room from pieces of sets from The Daleks and The Dalek Invasion of Earth. The Dalek ship in the third episode was populated by several Dalek props, including
