$5 Macro Lens - for use above and below the waves

Step 6 Mount the lens

So I forgot to take a few pictures here, so here's the rest of it without much ado:

First, reinforce the joint by cutting a short (2cm) long pieces off of the coil you made in step 3. Glue this piece on the outside of the joint with instant glue.

Next, press-fit the collar onto the camera and inert the lens. Tack the lens in place with instant glue, and remove the collar.

Seal the lens firmly in place with silicone glue, or some other type of flexible glue. Instant glue doesn't bond glass well, and lacks flexibility, so it isn't sufficient to hold the lens in place. I had my first few lenses pop out an inopportune times until I began using a flexible glue.

Let the whole thing dry, and you're ready to go.
