I’m restoring a 1915 OT Charles River and the ribs and planks are VERY dry. The planks have shrunk quite a bit. When I washed the interior after stripping the finish the planks swelled and the gaps between them decreased considerably. Are there any recommendations to restore your he dried planks? I don’t know if a few coats of “cut” boiled linseed oil will have much effect, or if there are any other tips someone can recommend.
