With the hull seams filleted and taped, I next turned to the bulkheads and hanging knees. These were filleted with peanut butter thickened epoxy, with the bulkheads being filleted on both sides. This will give great strength to the hull, and will also form watertight compartments in the bow and stern. To apply the fillets as neatly as possible, I used a gallon zip lock bag with a small hole snipped in one corner (after it had been reinforced with clear packing tape) as a sort of piping bag such that a pastry chef might use to decorate a cake. This allowed me to lay down a controlled bead of epoxy at each joint, which was then smoothed into rough shape with the rounded edge of a large tongue depressor. After allowing the epoxy to partially set up, I returned and gave it a final smoothing with a gloved finger wetted in alcohol. This gives nice smooth fillets that will require less sanding later on. Total hours: 16.00.
