Badger Hollow Observatory Construction: 2015-06-08

Siding is up on three sides
The fourth wall is sided and roof sheathing begun
The challenge: cover two 12' by 6' 6" sides of the roof...
... using 5 sheets of 4x8 5/8" plywood...
... while ensuring the end of each piece landed on a rafter
The ridge is left open an inch on either side for ventilation
The metal roofing is installed
A line is pulled to mark the locations for the screws
And the ridge cap is in place
