I got out the saw, and made some cuts. It was a real struggle to convince myself to make irreversible changes to the factory structure. Until now, all changes I've made were reversible, I could put it back to factory if I wanted, so this is now entering a new level of mods in my mind.
Sub floor/frame made with a combination of 2x3 and 2x2 SPF. I realize some people prefer cedar, but we are building on a pandemic budget and my phase I framing was all SPF. Extra strength added to the front section for mounting a seat base.
Used G1S 1/2 plywood for the decking itself. My main reason for going G1S was less voids in the sheet, and over all improved stiffness and flatness. After doing cuts I have found more voids than I would have liked, and the top layer is delaminating while cutting much more than I would have liked. Still unsure if the doubled cost of G1S is worth it. Measured everything three times before cutting into a $60 sheet of material. You'll notice that port side of the sheet has a gap with the hull, the sheet was only 48" wide and I needed 50" at the rear most end. I opted to offset the sheet to the Starboard side to prevent any gap on that side, and I will be hiding the gap on the Port side later on.
I realized after cutting that the material out of the seat structure that we cut outs could be recycled for making a rod locker. I wished in hindsight that I had taken more care when cutting to leave myself with more material to play with when recycling the cut-outs. I should be able to trim them to fit to hide most of my rough edges, with the exception of one hole used for the starting a cut.
It is great to see my vision taking shape so quickly. I guess the port side rod locker is now a sure thing.
Next I will be removing all the wood to begin priming and painting, and begin the process of sourcing my vinyl and carpet supplies.
