Some notes on home made riot shields
Okay. Some of you will need to know this.
Plywood shields proof against anything the cops can shoot at you, short of a Firearm, can be made from materials available at Home Depot.
You will need 1/4" or thinner plywood panels, 1" thick styrene insulating foam, and Gorilla Glue or Spray adhesive, like super 77.
A laminate made of styrene foam and thin plywood is stupefyingly light and strong. I made a motor vehicle out of this composite for my Associate's degree.
Demolishing it was more than a Chore, I needed a saw. impact resistant after a decade of dry rot. A shield made of the stuff, and curved slightly, will keep you safe against anything short of 9mm.
Face it with a quarter inch of HDPE sheet, or an eighth of an inch of sapphire fiberglass and resin, and now 9mm is having a hard time Killing you.
