Start with the fact that I follow directions only with what seems like herculean effort. So of course where the directions said to cover all the plywood sheets with 2 coats of epoxy before beginning, I didn't do that. I figured that it would waste a lot of expensive epoxy since a good chunk of the sheet would end up as scrap. So I cut my bulkheads and then applied epoxy. Now I know why the directions were written as they were. Turns out its alot easier to control the epoxy on a large flat surface than on small flat surfaces with lots of edges. So at this point fine, I "learned" once again to follow the instructions right? But then this happened:
I misread the dimension on the drawing for the location of the stringers (treated them as stacked instead of all coming from the CWL). But I already had one coat of epoxy on the bulkhead. I discovered that it is really hard to mark epoxy covered plywood with a pencil. So all my layouts would have looked really bad if I had followed the instructions. And fat smeared marks will surely lead to inaccurate cuts. So for now my plan for the nex ama will be to double epoxy coat one side of the plywood sheet, and use the other to layout cuts. Basically I will split the difference.
