Print full scale Rafter Plumb Cut Templates and Birdsmouth Templates
Fold template over rafter to mark or cut through.
Example :
Open page with full scale printable birds-mouth cutting template at current rafter angle and dimensions.
Total length of Rafter = 2523
Measure back 57 to form Plumb-Cuts, giving Rafter Top Length of 2466
With Rafter depth of 200 and Birds-mouth depth of 24 the rise from top of wall to top (high) end of rafter = 749
At an angle of 16° the total fall of the rafter is 680
With (level) overhang of 400 Total rafter run = 2370
