Examples of jobs, my softwood choice and Timber Merchants grades
Windows (see my Sliding Sash Window Blog)
You need decent close grained timber with a minimum of knots and other defects. This is because integrity of the design is required using fairly thin sections. You might also be painting or coating them to stand up to the weather and paint doesn’t like knots and shakes.
My Choice – the best Unsorted (U/S) redwood, you can find.
(don’t worry I’ll explain the timber merchant jargon in a bit)
The timber sections are bigger so small defects like knots won’t have the same negative impact and can look attractive but the joints still need to be tough.
My Choice – 4th’s ( IVth’s ) redwood
Other stuff of any quality
Where proper joints need some strength but you can work around any defects in the timber
My choice – 5th’s or 6th’s ( Vth’s or VI th’s) redwood
Carcassing, shelves in the garage, boxing in, rabbit hutches etc.
My choice – sawfalling white wood.
