Step 6 Glue

Squeeze out some 2 part epoxy onto some scrap and mix it up. Apply a thin coat of epoxy on one half, gently position the blade and LED assembly, add an extra dab of glue to the other side of the LED and blade then close the halves.

Next cut a few strips of waterproof sandpaper the rough shape of your plastic card, apply another thin coat of epoxy to the underside of the sandpaper strips and cover the outside of joined halves.

Clamp. wait. trim excess with hobby knife and sand all edges smooth.
By waiting until now to do a more thorough sanding you'll even edges on both sides and have a smooth top and bottom.

A word on epoxy:
As with most glue a good rule to follow is "less is more". This means that adding huge gobs of glue does not equate to a better bond. Most epoxy is stronger than the components being glued, using too much will result in a sticky mess with no added strength. Be smart, use enough to adequately cover the area you are working on, when you clamp it together some glue will ooze out but not so much as to glue the clamps to your project.

They're still around. I might be wrong, but I think they're a Fortune 1000 Company.

not only are they still around (and a staple to everyone I know), my neighbours to the East in Winnipeg are crowned the Slurpee capital of the world!
