Sketch with dimensions of additional views of the pack along with the gun.  Also note a small sketch of the backpack frame.  At the time we had no knowledge of what an "Alice pack" was.

Working from the sketched plans and photos I used my drafting skills to create this scale representation of the major elements of the pack.  Evidently I found something wrong with this because I x-ed it out.  Still, this looks pretty close.

I revised the previous plan and came up with this half-scale version laying out the major elements.

My next step was to create half-scale detailed plans of the major elements.  The names of the parts are my own, of course.

Finally, I made full-scale plans of the major elements.  This is what I came up for the main body of the gun.

Detail of the plans for the tip of the gun, including a supply list.  "Craigs" was Craig's Hobby in Tucson (long, long gone).  RS is Radio Shack.  K-Mart is K-Mart, back when people shopped at K-Mart.

Full-scale template for what would come to be called the motherboard.  Being on a very limited budget we ended up making ours out of 3/16" plexiglass, cut by Bryan on a bandsaw.
