Back round: I’m not a cook so an edible instructable wasn't in the cards. I can hammer a piece of metal though and a belt buckle is on the list on things I haven’t made. So I started by doing an internet search for “bacon belt buckles”. I didn’t find what I thought would be out there so I made what I had in mind.
Step 1: Make a copper sheet
Using a pipe cutter cut a section long enough to be a piece of bacon. Lay it up against a piece of ply wood and drag a marker down the side to mark a line. Use a scroll saw to cut the pipe in half. I used a 20 teeth per inch blade on the saws lowest setting.
Hammer both halves flat.
Be careful. Wear eye protection and always work within your experience.
Step 2: Cut and texture your bacon
Use marker to draw your take on what metal bacon looks like. Take it over to your scroll saw and cut it out. Lay it on a piece of carpet and use the wooden handle of a hammer to strike indentations along the copper. Smooth out the surface with a sanding pad.
Next take a piece of wire and shape it to look like fat lines for the bacon. Tape the wire onto the copper. Place the bacon back on the carpet and evenly hammer the wire into the it. As you hammer the wire will cut out from under the tape so make each strike count.
Repeat the process until you have the fat lines you want.
