How to make a Portal Gun

Step 11 Making the shells

This is a tricky and intensive part, at least it was the way I did it. The front handle shell was shaped from wire sheet, cut to shape, bent, and then cuts made at the front and back so the sheet can be bent over itself to form the curves. A few bangs with a hammer smoothed out the curves.

The large shell at the rear is made from chicken wire cut to shape and bent like before to make the basic shell.

I used pieces of paper to find the shape I need and made sure they fit around the paint can and the front section. I've added the patterns I used to make the shells. Sketched out mostly by eye. The front shell is on A4 and the back shell is on A3.
