Step 2.4. continued
From the leftover lengths of the shaped framing wood (the pieces with the corrugated bits) that I had already made, I had to extract the
corrugated bits from the frame pieces in order to use them as the decorative trim around the plywood rear wall.
See piece (b), fig 2.4.3.
I cut the corrugated bits out of the frame pieces just by making two cuts with my circular power saw.
It would have been a little easier to have used a bench saw, but because I was orchestrating the whole project outdoors it suited me better to use few tools as possible most of the time. (You know, in case the rain came down and I had to scarper inside with everything.)
Once made, I glued and nailed the corrugated trim to the sides and top of the back plywood wall.
At that stage the unit was lying face down on its belly.
The glue I used for pretty much the whole project was a two pot mix epoxy resin. Actually, it was the same stuff that I used for the fiberglassing except that I added a glue powder to it which meant that I could make it any consistency that I wanted (i.e. thick or thin).
I also opted for a epoxy resin undercoat paint for the complete project as well to ensure that all applications would be compatible.
