On one side of each disc, draw a line from edge to edge through the center.This forms a diameter
line.
On one of the discs draw a diameter line on the back side exactly at right angles to the line on the
front side. This disc will be the middle of the three discs.
Draw a 2" diameter circle and an 8" diameter circle around the center of each disc, on the
marked sides (and on both sides of the middle disc).
Drill a hole in the center of each disc.
