Every queen needs a round, metal hat, or "crown". This one is technically a 'coronet' as it does not close in the middle. The queen is Titania, queen of the faeries, daughter of Titans, and fittingly, her crown is made of titanium. The parts were designed using Autodesk Inventor and fabricated with a CNC waterjet cutter, in the traditional craftwork of olde. At TechShop.
Traditionally, faerie crowns are forged in a volcano. If a volcano is unavailable, you can purchase .035 sheet titanium from a number of online suppliers. For a 22" circumference head, you will need a sheet 7.5" x 19." Titanium is not essential to the construction, you can use steel or aluminum. That is, if you fear not to offend the faerie queen.
-Titanium sheet, 7.5"x19"x.035"
-Welder (TIG or Spot Welder)
-Work holding equipment
-Autodesk Inventor or another 2D vector design program.
Step 2: Design
The three parts of each side consist of two bezier curves. These can be rendered in Autodesk Inventor as splines or arcs. I have added extra thickness to the points where they will be welded that will be ground-off later. The circumference for this piece will be 23", so each half spans 11.5".
Step 3: Cut the Parts
If you do not have access to a CNC cutter or a faerie, the parts can be cut from sheet metal using hand shears or an equivalent stationary shear.
