We also made our own caulking tools or irons - six scalpels  / chisels of various blade thicknesses and a hammer. The oakum (hemp fiber soaked in pine tar) is sold in a thick rope-like spinned tufts, so we had first to uncoil and split them, set the tufts of smaller thickness and then spin them again. After that the oakum was hammered tightly in the grooves between planks. The caulked planking was subsequently covered with red lead tetroxide and linseed oil, puttied, sanded and finally painted.
