To make this flower, you will use the techniques in How to Use a Plasma Cutter and Basics of MIG Welding.
I made this at TechShop Detroit (www.techshop.ws).
Step 1: Choose Sheet Metal Material
Step 2: Cut Petals with Plasma Cutter
It is much better to start the cutter a little off the material and come in to cut. To activate the plasma cutter, lift the safety and pull the trigger.
Note that I originally chose four petals but added another when I realized it was not aesthetically pleasing enough.
