we put the cavity battens up,The first thing that happend was we set up a story rod to get the right heights so that weatherboards would be even the whole way round the house, we marked where the story rod met then ran a chalk line along and pinged it, this is to match the cedar boards upto.
we had to make sure that there wasnt a join on top of each other it had to be atleast 2 full weatherboards above, we used mitre joints throughout the joints this is to ensure that they hold for longer than just butting them up, each weather board had to be 162mm up from the below board, we came into a bit of trouble when we started following another line that had been put there by accident we then had to cut the nails out of the back of the weather board with a hack saw blade we took about 4 boards down and redid them, we also had to paint where we had cut to ensure that you couldnt see the joint or the weather wont take to it as easily. the spacings of the nails where 42mm up from the bottom of the weatherboard we had speacial nail plates which stopped us from putting smiley faces in the cedar board, we pre drilled then nailed. we also used a plumb with a string line on it to fix all the nails in a straight line. we used diamond head stainless steel nails.
