Helmet v3.0 – Rangefinder Polaroid Lens, Actual Lens

Convex Is Cool

Time to add the actual lens to the Polaroid part…

The plan is to use an old eyeglass lens…

Just need to cut it down to the correct size.

I used a straight-edge and an exacto knife to score it where it needs to be cut.

Top and bottom lines marked.

Repeatedly cut the line, using an exacto knife, until it cut all the way through.

Two cuts down…

Third cut down…

Fourth cut down. Now, final fitting…

The one side fits right into the slot. The other side needs some modification.

Did some more cutting on the lens so that it fit around the piece that juts out.

I then used my dremel to grind down the one side so that it matched the angle of the Polaroid piece.

Fits like a glove…

Front side.

What it looks like where it sits on the perspex block.
