Thought I would post a "how to" on making a hot wire since I needed to make up another jig for a end cut.
So I am making a end cut to fit a 1"x2" piece of wood into the end of 2" foam. This is for my shelves in the galley as well as some other locations where I may want to add some strength to a joint or span. I am trying to use all the foam I have for the build to cut costs and waste. I am using left over pieces of foam from the bulk head and roof to make my galley shelves. These pieces are too short by themselves so I will need to join them together. I was just going to glue the foam together, but thought that it would be nice to have some extra support for the center of the shelf and for the joint itself.
First I need a block of wood. A 2"x4" works good.
Then I will mark the wood where I want the holes for the wire to come through. I want the cut in the center of the foam so I measured from the edge how far in I need to be and then for the width of the cut.
