Picture of Build a prop Pulse Rifle (from card)
Having completed the ray gun prop, I spoke to the model for the Android bodypaint series and we decided that a sexy Sci-Fi girl needed a REALLY BIG gun. So I set about building some kind of pulse rifle.

This has turned into a labour of love and took FAR longer to complete than I would have thought possible at the outset.

Construction is 90% card with a few plastic bits and some bits and bobs of detailing. The main structure is a series of boxes glued together, a load of car body filler and finished with strips of card and a cool paint job.

The card I have used is high density 'show card', and high density card will do, the main structure is 1.5mm thick card (about 1/16") with the surface panels made of cereal packets.

Step 1: Barrel housing

The rifle is made in sections. I know little or nothing about real guns so I made this design as a hybrid of a few actual prop guns (Aliens and Starship Troopers) plus some game prototype designs I found on the net.

I wanted the final gun to be about 1 metre or 3 feet long. I used that as the basis of the gun and just made up the design as I went along, sketching each section as I went.

The main barrel housing is simply a rectangular box. I cut the top, bottom, two sides and two ends allowing for the thickness of the card in my calculations. Since the gun needs to be reasonably robust I added two internal spacer pieces.

Yet another confusing instructable. Can some explain to me what he means? I panic easily over small things. This looks great, but it's confusing.

Now when you say 'card' do you mean like Cardstock?

I have no idea what it's known as in the States. The main card type used here is known as 'Mountboard' if that helps. It's supplied by Daler Rowney as a border matt for mounting watercolours.

The pulse rifle from the Aliens movie was a combination between a Thomson SMG and a SPAS 12 shotgun.

I do like the look of yours.

Have you seen this?
