On Saturday we helped with a timber frame pavilion raising at the elementary school in town. The school is planning to use the pavilion as an outdoor classroom as well as a community gathering space, and a number of teachers, parents, and community members came out to assist with the work.

Once the pieces were laid out, we slid the notches together, then drilled and pegged the joints.
