How To Make a Cosplay Prop Weapon From Sintra

If you’re making any costume that features a gun prop, Aby has an interesting tutorial on how to make the gun from Sintra. We highlighted an armor build with the lightweight but rigid PVC plastic sheets yesterday, and though you could use craft foam or styrofoam to build a weapon, Sintra looks like a good choice. Aby’s tutorial is for a straightforward gun (it’s Ebony from The Devil May Cry), but you could adapt the instructions to make anything close: a blaster from Star Wars, a different gun for Blade Runner, or weapons in Battlestar Galactica. Before you take your creation to a convention though, be sure to check their weapons policy. Some conventions don’t allow even fake sidearms.

The tutorial uses Sintra, polymer clay, expanding foam, filler, paint, and a few other necessities. It starts with patterns, and Aby laid down the outlines of the guns in Photoshop and printed them. She broke that down into parts and cut several layers from Sintra to build up the gun to the proper thickness. She says:

Step 3: Assemble & Glue

Now that the various parts are cut out and you have an aching wrist for the rest of your week, you group the pieces together and glue them together.

Now, you can cut off and sand protruding edges or edges that are supposed to be more blunt.

Step 4: Fill small gaps

Of course, there will be some small gaps left that still tell that the components were not molded from one piece. To counter that, we use filler and spackle it onto the sides.

After the filler is dried, you have to sand the whole thing again, to have it as smooth as possible!
