Home-made Devastating Bombardment Template.

As I recently painted a Rocket Battery, RCA it now also means that I need a Devastating Bombardment Template. When I looked at the Battlefront webstore I was a bit shocked by the price of this template. €30,00 for a template that I probably won't use that much. Also at the moment I can't afford this amount money.
As I need this Devastating Bombardment Template coming Saturday at a tourney I had to come up with an alternative. So I decided to make one my self. The intention was to make one out of plywood but because I am overloaded with work this week I never could get one finished in time if I would use plywood. Thus I choose sturdy cardboard as an alternative because it is easy to cut and is much faster to work with. Later on I can use the cardboard one as a template when I am making one out of plywood.
I started to colect all the needed materials. Cardboard, sharp hobbyknife, ruler, pencil (not on picture), tape (wich I forgot to use), something to cut along to get nice straight lines, I used a trip of iron, something to use as stands (pictured are poles from the BF aircraft but later I decided to replace these with not used rivets because the aircraft poles weren't tall enough). And set to work.

Materials collected

Because the corners of the cardboard were at a nice 90 degree and all side were perfectly straight it meant that I only had to cut 2 sides to get a perfect 30cm x 30cm square of cardboard. Note: on the pictures it not always looks as a square but that is because of the angle the pictures are taken.

Next thing to do, drawing lines. Starting with drawing lines from corner to corner to get a big cross to determine the centre of the template. Beside these lines I draw 2 extra lines 1cm (later I changed that to 1.5cm) apart from the middle lines. Using the small bombardment template I draw the square in the middle. Now I knew which parts I have to remove. From the corners of the drawn square I went 7cm up and draw a line to indicate where I want the poles to be placed.

Drawn lines and more lines

Cutting out 4 triangles. This is done to get a better view under the template making it easier to place the template on the centre of the team / model. With a needle which I pressed through the cardboard I marked the positions of the poles and the centre of the template. Now were the markings are I drilled a hole by hand at the right size. Here is were I forgot to use the tape. Intention was to stick tape on both side were I had to drill so the cardboard wouldn't fray to much.

Then suddenly we have something that looks like a Devastating Bombardment Template. With the rivets that I now use as poles the hight of the template from bottom to table is 4.5cm.
