.:: Template Workshop ::.
I will try to describe in as much detail as possible the process of manufacturing large templates for making several kites of the same type.
Smaller templates could be drawn directly on to the card board.
.:: GETTING STARTED ::.
The first thing to do is to scale up the small image of your project to a full size drawing. I do this using the grid technique.
What you basically do is to place a grid on the original drawing with 1cm x 1 cm squares.Just take a look at the image, you can click it to enlarge it.
You would then calculate how big the squares are going to be if the full size drawing was say 3 meters wide.
You then draw the grid full size and transfer the image to the big grid. I do this roughly first with a pencil then use a long length of fiberglass to get more accurate curves.
I use end rolls of news print. These are available from the printers of your local news paper. You may need several pieces depending on the size of the finished project you have decided on.
.::CREATING THE TEMPLATES ::.
Once you have completed the full size drawing, this then needs to be transferred to large pieces of card board to make the templates.
Don't forget to add the seam allowance.
When your done, remove the drawing from the top and using a stanley knife, cut along the perforated line.
In the image to the left, you can see how I use this rotary tool to transfer the drawing to the cardboard that sits underneath the drawing.
Note that I am using the seam allowance line, as indicated by the dotted line, and not the actual pattern line. The cello tape is visible where the fiberglass rods were once held in place.
You can source larger pieces of the the cardboard at places where you get your car windscreen replaced. The wind screens come in very large cardboard boxes.
.:: USING THE TEMPLATES ::.
Now that you have made the templates, the next step is to cut out the pieces that make up the kite.
Arrange your templates on the fabric and run your hot knife along the edge.
In the image to the left, you can see how the pieces are cut out using the templates.
Do not let the tip of your cutter get too hot, this will burn the card and your templates will not last. To get the most life out of your templates, I recommend you use thin plywood instead of card board.
