20' Dome Sheathing
The precut triangular sheathing plywood on the 20’ dome was glued then stapled
with 2-1/2” pneumatic staples. Today's building codes may preclude staples
but they have more holding power than barbed nails. The intermediate triangles
were left open to provide footing for sheathing the upper sections. Generally,
start sheathing at the top and work down. A hand winch rigged to the rolling
scaffolding was used to lift the 1/2" plywood triangles 24' up to the
top of the 35' dia. 5/8ths dome.
