Templating & Layout

The windows, roofing, walls, and roof structure were torn out of the existing bay, leaving only the floor and the sole plates in place.

Builder Board paper worked well for templating the bay. Folds mark the location of the limestone sill.

Cutting in the corners of the house wall indexes the template.

An awl was used to pierce holes in the template along the plates. Later, a line drawn to connect the holes, or dots, would represent the outline of the plates.

A story pole marked the height and width of the opening.

For laying out the angled joists and the hips, a framing square is placed at a 5-in-12 pitch on the line representing the outside edge of the wall. The lines are extended to the back of the bay using a long straightedge held against the square's blade.

The ceiling joists will extend beyond the walls as lookouts to create the eaves.

The centerlines for the angled framing determine the intersection point of the hips, upper ledger, and side nailers.

The ceiling framing is assembled on top of the template using 3-inch construction-grade screws.

The two common rafters are aligned with and screwed to the joists.
