Pine Dowel Sizes available: 6mm, 9mm, 12mm, 15mm, 18mm, 20mm, 25mm, 28mm, 35mm The majority of solid softwood mouldings are produced from Scandinavian Pine and contain knots. They are easily worked with traditional hand and power tools and accept fixings and stains/paints and varnishes well. If an opaque coating is desirable ensure any visible knots are sealed with a good quality shellac knotting solution to avoid/minimise resin bleeding through the subsequent surface coatings. In a centrally heated home, lateral shrinkage of 2.5 - 3% is quite normal for machined profiles.
