Draw a line using a black permanent marker showing the where
the bend’s are.
Using your drawing, mark the centers of all the holes,
measuring from the edges of your panel using a #2 pencil and a ruler.
When marking the center holes in the middle of the panel, its
best to re-measure the panel to get your half way points. Take your over
all measurement and divide it in half.
Take your compass and put a marker in it. I used zip ties.
Draw out each hole. You can use a piece of paper to set the
compass to the radius of the hole and then draw the hole on the panel.
