More Rafters and Dormers

April 26. More rafters:

And dormer walls:

I looked at the dormer walls from the front yard, decided they were too narrow and too close together. Easy enough to move them apart and widen the dormers a little.

April 28. The second half of the ridge board goes up, and more rafters :

and the dormers get front walls:

A dormer from the inside:

May 1. 5 rafters to go:

Dormers, the far one has a ridge board, at the end of the day:

May 2. To make the little rafters for the dormer roof, I drew one full size on the dormer floor, then cut one out from a 2x8. This will be my template:

Here are four rafters installed on the west dormer:

I have also added top plates to the side walls. I will have to build little triangular sheathed walls to complete the sides of the dormers.

May 3. All the common rafters are installed:

Looking out from the ridge:

We put up the ridge board for the other dormer. Here are the dormers at the end of the day from the front:

Notice we took the gable end rafters down to notch them for lookouts. More on that later. Learn every day.

May 4. I framed a little triangular dormer wall. First I drew the pieces on the floor of the dormer:

I measured and cut the pieces. I had to tilt the base of the circular saw to bevel the ends of the lower boards. The angle of the cut, which is the angle of the roof, is 40 degrees. The assembled wall frame:

May 5. I built 3 more triangular frames, for the other dormer walls. We measured and cut OSB sheathing, nailed it to the triangular wall frames and nailed the walls to the top plates, to the adjacent wall and to the rafters:

I cut more little rafters and we installed them on both dormers:

May 6. A bit of fun at the edge of the third floor: installing fly rafters. I took one of the gable end rafters and marked it every two feet with my carpenter's square for a notch I will cut for 2x4 "lookouts." These will support a 2x6 rafter called a fly rafter that will stick out beyond the wall of the house. This picture shows all the tools required. The circular saw makes straight cuts, the reciprocating saw cleans up the cut so that it goes to the base of the cut...

...the hammer is used to knock the wood out to make a notch:

Here is the rafter with all the notches cut:

I clamped an 18-foot 2x6 fly rafter to the gable end rafter and inserted 2x4 lookouts, and nailed them in with the nail gun:

We installed the gable end rafter with the notches up. I trimmed the ends of the fly rafter to match the gable end rafter and three of us threaded it through the last rafter bay and dropped it into the notches. Here it is nailed in place, to the first common rafter after the gable end:

We did the same for the others. Here is the south east fly rafter:

The west side from the ground:

One more task for the day: cutting and installing the jack rafters in front of the dormer walls. Here is a little 4-foot rafter:

Here are four installed in front of the west dormer:

Here is the front after the long day. All 2x10 rafters are done:

May 7. The dormers still need a few special rafters where the main roof meets the dormers. The valley rafters will go from the intersection of the two ridges to the double rafters on the sides of the dormers. They need a double bevel cut where they meet the ridges. I've had the old song "Down in the Valley" stuck in my head for days thinking about these rafters. Here is my first try at a double bevel cut:

The other end needs one bevel:

After a couple of tries and retries and recuts, I got the first one in. The arrow is pointing to the valley rafter. It is in the same plane as the common rafters on the dormer:

I cut the others, got them all done. Here are the two on the west dormer:

May 8. I cut 2x6 fly rafters for the dormers, nailed 2x4 blocks to them and nailed them to the gable end rafters. The block spacing is 2 feet or less. I thought that would be sufficient for strength and it appears to be, but I might have to sneak more blocking in for soffit support:

From the front. Also seen here: we (meaning my son and my brother) have nipped off all the floor joists with a reciprocating saw to make way for the plywood decking:

One more view, from the scaffold that has not been installed yet :-)

Next: Fascia.
