After circulating around and watching you practice, I have a few observations.
1- It is a good idea to frame your through wall first. It will be easier to stand up both of your walls and will help you in your lay out.
This shows the difficult way (to be avoided):
You can see it will be more difficult to erect the second wall.
2-I will set the original line for your project. Do not assume the plywood will be the exterior of your building.
3-Please cut the notches for your cripples for above the door and window out of longer sections of 2 x 4 and then cut them to length – it will be easier and safer!
First mark it out and then rip the length of the lintel
then the short cut:
then the length:
Clean up the cuts with your knife:
4- When squaring your wall, nail the lower plate to your platform, ideally on your layout line so that the nails also will serve as temporary anchors to prevent the wall from slipping or kicking out as you lift:
5- Most of you mixed up your nailing sequence and forgot to nail in your ladders before installing all of the studs. In this case the ladders on on the wrong side of the studs:
I will be checking to see if you install the rough sill prior to the kings beside the jacks!
6- The interior wall measures are given to the centre of the wall; you will have to translate this to the inside edge of the lower plate so you can see where it belongs.
I have yet to evaluate what you have done – that is where we begin tomorrow!
See you all then,
