I started by cutting the patterns from the template I made out of poster board for the shoulder skin. Then I traced them onto the MDF sheets, cut them out, and sanded the edges. Next I put ona coat of grey primer, and then metallic silver. Luckily the paint made the MDF bendable, so they were really easy to wrap around the shoulders.
I attached the collars to the shoulder with machine screws and lots of washers and nuts the keep them at the right distance from the shoulder piece.
I connected the strips to eachother with little MDF plates I cut out and joined with more maching screws. These aren't entirely accurate for the '63 Dalek, but I needed to use them to make the collars work, and I think they still look ok.
