How to create a Balisong (Butterfly) Knife using Erector sets

Have you ever wanted to have your own legitimate Butterfly knife?
What you will need for this tutorial-
-An erector set (NOTICE: Depending on how many pieces are in that set, buy more accordingly)
-A small sheet of plexiglass, thickness based on your preference (Don't make it too thick, or too thin)
-Spraypaint (Optional)
-A wire cutter
-Dremel (Cutting tool/Sanding tool)
-Drill
-Clamp (To clamp down while using dremel and drill)
-2 Sizes of screws. The default small ones from the erector set, and slightly larger ones of the same diameter. I don't know if these come in the set as well.
