Weatherboards from boundary up to soffit lining

As boundaries done yesterday, today we worked on the space from the boundary up towards the soffit lining.  
This was done by measuring 159mm from the bottom of the boundary board at each end of the wall.  A chalk line was then held from each point & used to create a guide line to run the next board to, which would ensure that everything remained level.
This gap presents a gap large enough to allow the ridged section to sit over the weatherboard with a 2mm gap between (as seen in picture).  This is very important as it allows for air to circulate & to stop the boards buckling if water gets in and expands the timber.  

The same nails & methods were used to make the fixings  as we had done for the boundary weatherboards the day prior.  

When attaching the nails along the length of the board, these were only partially nailed in, to allow adjustments to occur if necessary (if they started straying from the chalk line level marked out).  Once all nails had been attached along the board these were then nailed home.  To do this you have to place a firm hand down on the board to push it close to the wall.  Had to make sure not to nail it in too deep, the head of the nail should sit on top of the board.  This is because water can easily penetrate around the nail head if it is pushed too far in.  
I actually found it quite hard to hit the nail, as the head is shaped in such a way that the hammer can slip off easily.  A tip that Richy gave, was to sand your hammer head so that it has grip on it, as we have to try and avoid hitting the board as much as possible as it results in easy damage as the cedar used is very soft.

For the board that ran against the soffit lining, this had to be ripped to the correct size.  This was done by again marking 159mm on the board below.  Once done, the measurement from this point, to the soffit lining indicated the height of the following board above and what thickness it had to be cut at.  This was done by using a skill saw & then attaching as normal.
