Step 1: Materials
pliers for bending metal
file for smoothing edges
nuts and bolts
Step 2: Cut the Metal Strips
smooth the rough edges with a file
Step 3: Bend
Step 4: Close Shape With Screw
align the metal edges so the interior of the curve is smoothest. Put the screw hole near the edge so the amount of metal overlapping in the interior is minimized.
drill a hole for the screw to fit
assemble so the head of the screw is inside of the form and the remainder of the screw extends outward. Secure with a bolt.
