Before the frame legs set up, you should make sure clean the floor and you draw the base line to use the trammel arm. It will be easier to make a right angle. Afterthat draw the all lines follow the Auto Cad plan as well as set up the frames. All the frames has to be level and fair so when you set up these, you just chek each side of the frame by dumpy which means, clamping storyrod each side of the frame and then someone looking the storyrod by dumpy to make sure the both storyrod lines exactly same. If you think the both line definately right, you should tell to others then they screw the frame and glue the wedge. This way is going to be continue to last station.
Young Tae, also remember that the centerline must line up. You could also explain about the need to keep the frames plumb. This is done with a level. Each frame is numbered and the location of this must match the grid.
