Rafters and Scaffolding 28/08/2012

Capping the end of the rafters with a metal blah was the first thing on the books today. With the rafter sitting flush up against the top plate, we had to check the wood and insert the metal blahs so they sat flush. Scoring where the meatl blah would sit, we then chiseled it out and nailed them down. Any over hang would hinder putting up the weather boards later on down the track. The outside rafter, was then nailed every stud with a 4inch nail to give it more support.
Some scaffolding went up along the back of the house. Then a team of people had to check, and nail in multi grips on all of the tailing. This, securing them to the top plate properly. Then hammering nails in on either sides (both on 45' angles for maximum achorage). A string line was then set up and run along the back of the building along the top plate to see if the house had moved at all. Along with dodgem blocks them were checked. The plumb bob was also set up at the top of the frames of each corner, just to see if they were still straight.

Then a team of professional scaffolders came in and started erecting a walk way at roof height around the north and west face of the building. Once up, we started tacking our rafters in. One by one, they were lifted up, sat on the marks from previous and nailed in. We went back today using the string line and the plumb bob to check to make sure house hadnt move over the period of time. With 21 students in the class, you can feel ampul shocks through the wood. But not enough to move the frames from the bracing.
