In this video you can see that the bow and stern panels are joined with a butt block. I also place 2 backing pads for the beam lashings. First I determine the location of the butt block and the backing pads, then the surface is sanded with 80 grit sandpaper and cleaned. Then I mix some epoxy and apply it on one side of the butt block and backing pad. I let it stay for a couple of minutes so the plywood can soak in the epoxy. Meanwhile I am adding a cotton fibre adhesive filler to the epoxy mix and thicken it to a "mayonnaise" consistency. Then I apply it to the surfaces and place the parts on the spot where I want them. In the case of the butt block I use some brass panel pins to hold the butt block in position while epoxy and cotton fibre glue sets.
