In this episode of the Art of Boat Building I build a caulking wheel for caulking a wooden boat. This shipwright tool is used to press cotton caulking in the seams of tightly spaced Atlantic White Cedar planks. Small wooden sail boats that are carvel planked, like the Haven 12 1/2 generally have tight seams that require the use of a caulking roller. The hand crafted walnut handle is beautifully set off by the brass accents.
