Installation of the rafter
I assemble the materials which I cut
I hit the rafter which I cut and brought down with a course thread (wood screw) one by one
It is quite thin when I look at the rafter of 3cm *4cm in this way
it is a common electric screwdriver not an impact driver, it is quite hard
It is “sense” in the space beating against the bar
It will be distance like this when I think about the strength of this rafter and strength of the 5.5mm veneer
Because I think that the middle will be vulnerable to vertical power when it is this state, I put some reinforcement midmost
Because the coping moiety costs terrible power lengthwise, I put reinforcement in lengthwise direction
