A small square of 22 gage sheet metal. I bought a 22 gage sheet at the hardware store for about $8.00.
Step 1: Draw Out Your Butterfly
Once you have your design, retrace the perimeter of the wing with moderate pressure. This will cause your drawing to separate from the rest of the paper. Now you have a stencil for your butterfly wing.
Step 2: Cut and Shape
Remove any coating from the metal with sand paper or a rotary tool bit.
Place the wings together and clamp them in locking pliers. Join the wings with solder. By doing this the wings will be a mirror image of each other after you separate them again.
Use what ever method you prefer to shape the wings. I used a combination of my scroll saw, a rotary burr, and needle files.
Once the wings have reached your desired shape, use a torch to separate them. Both wings will have excess solder on them. To remove the majority of the excess, I held each wing with pliers in the torch flame and scraped the molten solder off with a razor blade.
Step 3: Make the Body
Mount a wood nail into a drill press. Transfer the registration marks from the paper to the nail with a permanent marker. Spin the nail round and use a file to cut out the body.
Once you have the body cut, snip it off with pliers. Gently flatten the body by using a smooth faced hammer on a smooth surface.
Refine the body with needle files and sand paper.
Step 4: Make the Antennae
Use a triangle file to score a line on the top of the bug head. This will serve as a guide for the scroll saw blade.
Mount the body in a wooden clamp and use a saw blade to cut a groove in the head.
Extend a paper clip and fold it in half. Gently hammer the apex of the paper clip until it slips into the cut groove. A bit of solder will secure the antennae in place.
Step 5: Emboss the Wings
Gently and evenly hammer the wings from both sides. Both wing are now embossed.
Step 6: Convex the Wings
Place the wings over a scrap piece of wood. Hammer the head of the bolt evenly over the entire wing. As you go along, the wings will take on a convex form.
Step 7: Solder
Place the connecting piece between the wings and solder them together. This is the time to remove any excess solder which runs onto the wings.
Solder the antennae into the head and then place the body between the wings. There should be enough solder left between the wings so that all you need to do is apply heat.
Step 8: Polish
To get in-between the body and wings I dulled a razor blade on a file and then folded a piece of sand paper over it.
For polishing in the same place I used a string with polishing compound on it. Polish the rest of the butterfly with a small buffing wheel.
