End pours

I decided to do the optional step of end pours. This is simply pouring a fairly large amount of thickened epoxy into the very tip of the bow and stern hull. On some smaller kayaks, end pours are accomplished by hoisting the hull vertically on end and pouring the epoxy into the hull, then letting gravity keep it in the tip. However, in a hull the size of a Mill Creek 16.5, it is easier to use the dam method. I cut some corrugated cardboard to a shape that would fit snugly in the end of the bow and stern. I covered the cardboard with clear plastic packing tape, and also used the tape to seal the edges against the hull wall. At this point I could pour epoxy that had been thickened with wood flour --but was still pourable--into the chamber created by the dam. I ended up doing a pour at both ends in two stages, to reduce the amount of heat generated by the curing epoxy. It was an unusually cool evening, and yet the heat of the chemical reaction could be felt through the wood and fiberglass of the hull wall. These end pours will add weight to the hull, but also will add strength and impact resistance. Total Hours 30.75.
