Howdy Merlin,
First, welcome to the forum, we are glad to have you here. Now i havent built a full sized Dalek, but since you raised the thread, I thought I would offer this link to a card model of the Dalek.
The Ultimate Dalek Factory
The model is a free download (simply print out the parts, cut out and assemble with glue.
And here is a link to the plans for a full sized dalek :
They were originally published in the Radio Times 10 year Doctor Who special in 1973.
(above, photos of completed card models of the Dalek)
again, welcome to the forum and have a good day,
Greg aka GEEDUBBYA (GW)
