Step 31: Crowsnest Assembly
Part 1
A:
On flat level ground, lay out (320) Crowsnest Back and (321) Crowsnest Front so they face each other and
the countersunk holes on the (321) Crowsnest Front face out. Using the middle pilot holes as guides attach 2
(322) Crowsnest Joists with 2 (S3) #8 x 2-1/2” Wood Screws on the back and 2 (S4) #8 x 3” Wood Screws on the
front, per joist. The distance between (322) Crowsnest Joists should be 12-1/4”. (fig. 31.1 and 31.2)
B:
Tight to the outside of each (322) Crowsnest Joist attach 1 (323) Crowsnest Gusset with 1 (S7) #12 X 2” Pan
Screw per gusset. (fig. 31.1 and 31.2)

Attach each (323) Crowsnest Gusset to (321) Crowsnest Front with 2 (S4) #8 x 3” Wood Screws per gusset.
