Step 2: Chest Plate
2. Take the measurement of your throat to high abdomen. Mark that on the metal.
3. I made a rough estimate at what the costume should look like. I simply free handed the curves on the sheet metal.(DONT FORGET THE CIRCLE FOR THE ARC REACTOR)
4. Next, I created a small piece to position below the top half of the chest plate.
5. After that, you should have two pieces that you will connect together. To do this I 'eye-balled' it and drew dots where i need to drill the holes. I drilled the holes and joined the two pieces together with a nut and bolt.
6. Next you must create a harness, so that you can put the chest plate on your body. cut out 2 long strips of metal and drill holes to the chest plate. Join the 2 harness strips with the chest plate, using nuts and bolts. at this point you should be able to put the wear the plate.
7. to complete the torso plates, I added a back plate, using the 'drill-nut-bolt' method, then I also added some strips of metal to the front to get a bit more detail out of the chest plate.
8. Make sure you bend the chest to make it accurate to the movie. the chest should stick out, it shouldnt fit flat!
9.Try it out again, and duct tape the areas under the plate that are unstable.
1. At the completion of all that, you can use hot glue, and glue a few lines on the chest plate, this will simulate the welding marks on the costume.
2. After doing that, spray it all down with silver spray paint, garnish with some black for a 'used' feeling.
