I used my drill fan to place 9 equally spaced holes on the hinges and angles. I like this little drill tool. But once an angle is drilled it becomes a better template for drilling the next angle.
First I opened the fan all the way to drill 2 inch spaced holes. This made my fan stick open and I almost couldn't get it done. So I used every other tooth in the future to get 2 inch holes equally spaced. They aren't really 2 inches. They were 1 29/32.
Drilled every other hole 9 in all
Spread wide for 9 holes. Avoid opening all the way
