thanks i will pay you for a copy and shipping ill pm u rye

Places like Kinko's have an item called a percent wheel, we used them in the printing industries too. Saves you a lot of thinking and math. You just put the ring on a line showing a size you have and it will show the percent for the size you want. Saves a lot of time and thinking.

160% will give just about 80 " wing
