Brent, I ordered a new fresh manual from Dumas, and they have deleted part of the directions you refer to. Section 24 now starts of with....

"Draw a line on the FB deck 1/16 in from the edge of the cabin on both sides"............



This was deleted on the updated manual - "Make up the marking guage in Fig. 8. Use the guage to".....


Section 24 is to help you determine true center of the deck and the proper placement of the FB-1's

let me know if this helps
