Plug in your battery and make sure all your LED's light up. Then mount the center top ring assembly to the inner ring assembly by lining up the three bolts and tightening them until the bottom of the top ring assembly sits just above the inner ring assembly. You can add a dab of glue if you want to the bolts to make sure they don't come loose.
Now press the entire assembly into the backplate assembly- note the orientation, making sure everything is aligned correctly. If the fit is really loose, you can put a couple dabs of glue between the wrapped copper wire sections and the backplate to hold everything together.
That's it! Now go finish your Iron Man armor suit...... :)
