Here is a fin template I made in PowerPoint for a quad setup -- but you can make a file template for any setup. The template consists of parallel lines that are 1/10" apart. The lines are at the toe in angle I chose for the board. I printed on two 11x17 size pieces of paper and taped them together. Depending on the size of the board your paper may need to be larger or smaller. The lines were layed out using PowerPoint and when I printed I made sure the lines were the correct size. Here is a view of one side on the template.
Here is the template aligned to with the stringer:
With a square, I measured in from the rail 1.25" and used the closest line to that measurement
I then took a punch and made a light indent in the hotcoat at the base of the fin and at the front of the fin (along the toe in line). This gave me two points for each fin to create the fin line. I used a punch becuase the board was painted black in the tail area – you could use a pencil for unpainted boards.
Now just connect the dots and your fins lines are there. I used tape – again becuse of the painted board - but one could use pencil. Send me a message and I will send you my PowerPoint PPT file to use as an example. Have fun!
