Step 6Adding shape to the barrel and stock
The barrel is starting to take the right shape now but it still needs a bit of work. To make the barrel wider you will need to start adding material to the barrel. Sheets of cardboard are cut to shape to provide nice straight edges, although this step could be done with more pink foam, cut and then sanded back to the desired shape.
To keep the structure strong (it is the area you hold the weapon after all) it is made up from several triangular prisms, these shapes are strong in all direction and easy to construct.
Cut a piece of card 64.5mm wide wide 400mm long (this dimension can be made up with several shorter pieces). Score the card along the width to create the sides of the prism, these should be 5mm, 25mm, 24.5mm and 5mm wide. Fold the card and glue along the first 5mm length. Fold the card into a prism shape and glue this edge to the other 5mm wide edge. This should form a triangular prism with a right angle.
Repeat this process to create a second prism for the other side of the barrel and for 2 more prisms with sides of 5mm, 15mm and 14mm. Next cut a larger piece of card, 400mm long and 154mm wide. Score this piece into widths of 15mm, 10mm, 25mm, 54 mm, 25mm, 10mm and 15mm. This will wrap around the prisms and the barrel to form the desired shape. Glue the prisms to the larger sheet. A picture speaks a thousand words so I've included a doodle of this all.
Finally cut a notch out of the card in the same shape as the injector notch, then glue the whole shape to the barrel. This provides the added bulk to the barrel.
With that done it's time to add some shape to the stock. This I have less photos of but it is fairly straight forward. Cut some 5mm thick stips of foam from the block, this thin sheet of foam will be flexible enough to provide a curve to the stock. The foam will be the same width as the stock so start by building up the edges of the stock. Then create 2 'sheets' of foam by glueing 2 pieces of foam, 160mm long along the long edge. Carve the circular detail into this sheet and then glue it to the side of the weapon. Cut around the stock to make the sheet exactly the right size.
