Step 1: Eye Pieces
Step 2: Eyepieces 2
Now hold this up to your eye with the long shoulder part of the bottle going across your cheek towards your ear. You will find that different parts of the edges dig into you, so gradually snip those away until the shape fits neatly to your face and feels ok.
Cut another one to fit the other eye.
Cut a very small slot (5mm or1/4" long) on the nose side and a slightly longer one at the ear edge. These will be for the straps.
Step 3: Eyepiece Rim Lensholder
Step 4: Lens
Cut a circle of the clear plastic that will fit tightly inside the lid behind the hole you cut. Screw the bottle tops (lens rims) back on to make sure they fit ok.
Take the bottle tops off again, remove the lenses.
Paint the bottle tops (lens rims) with a metallic paint (brass or copper) and leave them to dry completely.
Paint the eyepieces black or perhaps dark brown and leave them to dry completely.
Step 5: Assemble and Complete Goggles
Put each lens into each lens rim and screw onto the eyepiece.
Using narrow strips of duct tape, cover the edges of the eyepieces. This is optional but the edges will feel sharp against your skin if you dont cover them somehow. You could do this by gluing on narrow strips of leather, but that is the for the perfectionist perhaps.
Cut a small strip of inner tube or leather for the nose strap and push through the slots you cut in the nose edges.
Cut long straps (20-30cms or 9-12") for the headstraps and push each one through the slots you cut in the ear edges of the eyepieces.
Away you go in your Flying Ace Steampunk goggles!
