Below is a link to a Youtube video of a shipwright using a version of kigoroshi for planking a wooden ship. He uses a metal roller, and diring a second step, a hook to prep the joints between planks before caulking. This entire series of videos is very interesting for those into traditional techniques in woodworking. https://www.youtube.com/watch?v=Ox8r...-r1dFwgL&t=172
