Suspect 27 said:Could you provide a link to the buttons and the clear acrylic thing
I could, but probably no need as 'Mooncrest Models' now sell a perfect 1/6 resin Fresnel through their site www.mooncrest_models.co.uk for about £4.00. Get the MK2 version, as the MK1 is for a real police box and too big for a TARDIS.
If you are looking to build a different scale, then all you need to do is measure the width of the Fresnel and buy a pack of clear plastic buttons of the same size. Get plain ones. You will also need a plastic disc of the same diameter for the centre part, and these are listed on eBay as 'clear acrylic disc'.
