Over the past month, Punished Props' Bill Doran built a 1:1 scale replica of the alien assault rifle from District 9 to unveil with us at Comic-Con. Bill's build logs and videos will walk through his design and fabrication process, and his finished piece was unviled with a surprise at SDCC. Place your questions for Bill in the comments below! Here are parts 1, 2, and 3.
Here it is: the final part of the District 9 Gun Prop build! Fortunately, the molding process was fairly painless and yielded some very useful molds. When it comes to casting, having good molds can make or break a project, especially when you need 24 of something, as we did for this whacky alien gun.
Most of the pieces for the gun were done with simple dump molds. This means all I had to do was mix up some Smooth-Cast 300 resin, tint it with a little SO-Strong black, and pour it into the molds we made. The only fancy business we did was to tap the mold around a bit to make sure no bubbles were trapped.
This process was used for the top scope pieces, the barrel pieces, some of the side greeblies, and all 24 of the tubes that stick out the sides of the barrel length.
