I changed the roof on the machinery shed in the autumn of 2009 and have wanted to finish the project by making a new
As usual I am using larch since it is very weather resistant (and I still have a load of it). After mounting it will be painted.
The pattern is traditional Swedish (although I live in Denmark). The wider boards are 1x5", and the thinner strips are 1x2". The wider boards are nailed on using 3" nails and the thinner boards are nailed using 4" nails. That way each board has got 2" of holding in the frame.
The wider boards are placed a small distance apart, and the thin strip covers this gap and the nail passes through the gap and into the frame.
On the bottom of both parts, a vandnæse (directly translated into water nose) is sawn. It is a 45 degree slope that will prevent water from seeping into the end grain and cause premature rot.
Traditionally in Danish building this is omitted, probably because the carpenters like the idea of being able to secure a job some years ahead by making sure the panels have started to rot at that time.
Another thing that is important to ensure longevity of the wood is to make sure it is oriented correctly. I follow the idea that the heart wood should face outwards. And the grain direction should be so that if you wanted to plane the board, you would have to do it vertically down.
On rough sawn wood, you can see the small ends of the wood fibres pointing one way. They should all be pointing down. That way the wood will be protected the best possible way against damage from the water.
The part of a house that I
don't now do know the English name of. :-)
Close up of the water noses (perhaps there is even an English word for those as well?)
