In this, my first instructible, I detail how I (with assistance) created a variation on a prop from the BBC show Torchwood. The prop in question is the "Vortex Manipulator" found on the wrist of Captain Jack Harkness. Below is a screenshot from the show of the item we are trying to replicate with some small changes. My intent with this instructible is to show how I went through the data collection, model manipulation, replica testing, mold making and pewter (yes, molten metal!) melting, pouring, and finish work.
