tongue is exactly on the corner. Along 

 a-c draw a line, and this will give you 

 your plumb cut. 



Now from a measure down 7' 3" to 

 point d, and, in exactly the same way, 

 using point d as you did a, strike d-e, 

 which will be parallel with a-c. Then, 

 in the position that we have it illustrated 

 d-e-f, draw the horizontal line of the 

 heel cut. When finished, the heel cut 

 should have its dimensions as detailed. 

 The lookout, from d to the end cut, is 

 12 inches. 



Saw these cuts exactly square with 

 the edge, and lay out another rafter in 

 the same manner. Nailing a small block, 

 which is substituted from the ridge 

 board, on the plumb cut of one piece, 

 put these rafters into position on the 

 plates. If the work has been accurately 

 done, and the plates are just 12 feet 

 apart, the heel cuts will come exactly 

 right and square with the plates. If 

 not, then you must cut and fit the rafters 

 until they are satisfactory. When accu- 

 rately fitted, use the best one as a pat-

 like it. Select a piece of straight floor- 

 ing that is two feet longer than the width 

 of your cottage, and nail the rafters in 

 place, as illustrated in Fig. 17. 



They are also spaced 24" on centers, 

 and should be accurately layed out on 

 both sides of. the ridge and on the plates.
