Second instalment….I do not see too many blog views in the past few days…..I hope you will all take advantage of these posts to assist yourselves!
In the next photo you will see the plates with the layouts on them, a corner stud and two lintels – one for the exterior door and one for the window, the interior door will not require one as it is a non-load bearing wall. See the post a few days ago for the calculations, but suffice it to say that the width of the window/door plus 4 inches is the correct length for the lintel…..if you need clarification, ask in class. Notice we are starting the build on the through wall!
One Lintel is made with a 2 x 4, the other with a 2 x 6. This is according to the table of lintels you are given and is dependant on the width of the opening. Make sure you put the right lintel in the right place! Please take care to make all of your joints flush on at least one surface….you will be graded on this.
Now it is time to start nailing things together. You will have to sequence your nailing correctly, so start with the “ladder” for the interior wall and the jacks for the window/door opening. The length of the jacks is dependant on the height of the door, so even if you are starting on the wall with the window, you will have to cut four jacks based on the door. The jacks will be in the right place if the rough sill is temporarily placed as a template on the lower plate, and the same goes for the “ladder”:
After the jacks are nailed in, you can calculate the place for the rough sill and nail it in….
Nail up the ladders as above, respecting the approximate “thirds” rule I mentioned in class.
Next, you can place the cripples under the window, the corner post and the other studs that will not get in your way to prevent proper nailing sequence:
The wall begins to take shape! Now it it time to cut and install the cripples on the top of the opening (if this is a door, there will only be cripples on the top). Cripples here are a precise fit, so make sure they look good or you will loose marks. We can install the upper plate and the king studs on either side of the jacks at the same time. I need to see a minimum of 4 nails per king and 2 nails wherever there is a butt joint:
Then you can finish all the rest of the common studs:
Now it is time to square the wall: Start by nailing the lower plate on the chalk line at the layout mark. This will make a straight plate and prevent it from moving while you manipulate the wall. Then make sure your diagonals are equal and nail a 1 x 3 as a stabilizer when you lift it. Please use only 2″ nails for this….
Beautiful!! The wall is ready to be lifted, placed and nailed. The nails have to be in a joist and there has to be “enough” of them. How much is enough? Depends on your wall and how warped it is. Please help me help you by putting enough and in the right places!
The end of the wall will have to be plumbed and braced:
In the above shot, the next wall is being built using the same principles as the first wall. Nailing sequence, quantity and nail placement are all evaluated, so take care. In this case, we are installing the 2 x 6 lintel as per the plans.
After the second wall is raised, we start on the interior wall. As per the plans, our measures are taken from the outside of the siding for the door opening and the 16 O.C. is taken from the end of the interior wall:
The wall is placed according to the plans and it is important to chalk a line before you raise it to be sure it is in the right place.
Here is the wall ready for lifting…..note there is no lintel, no jacks: just a rough header for the opening. This is because there is no load. The opening is 2 -1/2″ larger than the door schedule given to you on the plans:
Finally, the last wall is raised, placed, attached and braced:
The final step is to install the cap plates according to the rules: no cap plate can be less than 4 feet long and the joints must be tight.
Confusing? I am certain that some of the process is to some of you! We have two days to practice this project. Take advantage of the time allocated for this so you can complete the exam with a success!!
See you tomorrow,
See you all tomorrow
