Plastic is an incredibly versatile material and it is everywhere. With a little ingenuity and elbow grease you can make it into just about anything.
First off, there are toys. At any Steampunk cosplay event you can be sure you will see souped up Nerf guns and squirt guns that look like they walked right out of an H. G. Wells story. But keep in mind that if you want to paint a plastic gun that spray paint will chip over time. If you scour your plastic surface ahead of time with steel wool, sand paper or even a kitchen scouring pad you will create pores for the paint to adhere to and it will last much longer. Kinex is a line of plastic engineering toys so it is a great way to get lightweight and cheap plastic gears that you can paint to look like metal.
At the Form and Function session at The Asylum one of my favorite items was a remote-control Dalek toy that a maker Steampunked by adding metallic paint and little makeshift boiler on the back.
Plastic pipes like the ones you can find at the hardware store are also really useful. Just like plastic guns, they need to be roughed up before you paint them, but they are relatively easy to drill into with a small electric drill so they are easy to embellish. Major Quicksilver had an amazing “power glove” that he built by attaching a leather work glove to the interior so the fingers were flexible even though the gauntlet was rigid. It was enhanced by flexible plastic tubing and a leather strap that attaches to the upper arm.
You can also get the look of rivets without having to use real metal. If you search for “half pearls” on eBay you can find these great little half-spheres that look just like metal rivets, sometimes without having to paint them. The Major warns that you can find one with adhesive on the backs, but they are much more expensive than getting the kind you glue on yourself. And if you are attaching them to EVA foam hot glue will hold them on really well. An audience member also mentioned that dried peas or lentils can also do for rivets in a pinch, as long as you don’t mind a little irregularity in the shape.
Another great use for plastic is if you have to make something hinged. Sure, you can use real metal hinges that require screws but if you want a quick and easy hinge you can just cut plastic packaging like the top from a butter tub or the like into strips. Attach one end of each strip to the pieces you want to hinge and you will have a flexible and lightweight connection. The amazing giant hand at right had metal hinges on one side and plastic on the other. He was able to manipulate the fingers by pulling strings attached to a leather glove on the other side. In case you are thinking of doing something similar, he let us know that the thumb was the most difficult part to get to move, so he used his pinky finger instead, ergo the three-fingered hand.
The good Major also told the crowd all about a wonderful malleable plastic called polymorph. It comes in the form of little beads and you can melt them in boiling water on your stove. After they become gel-like and come together in a glob you have about 5 minutes to mold it into any shape you want. And if you don’t like the result you can just put it back into the hot water and start again. Of course, you have to be careful about burning yourself when you take the polymorph out, so if you use something like welders gloves it will protect your hands. It usually comes as a transparent plastic, but you can add dyes or paint it later. Once it is solid it is a great material to drill into or file.
If you want an antiqued look to your paint jobs you can use a dry brushing technique. This is done as the second layer to add a bit of a weathered look to your surfaces. For instance, if you are trying to get the look of copper armor that has begun to oxidize, you should start with a solid layer of copper paint before you add the touch of turquoise to make it look tarnished. To dry-brush, add a glob of paint to your brush (this is a good use for old brushes) and remove most of the paint on a newspaper, magazine, etc. Even if you remove most of the paint there will still be just a bit left on the bristles, and you can apply this to your finished project.
