The floor took over a month and had a lot of expensive parts. However I was unhappy with it as there was air in the layup. This was a non structural fault. It was caused by making the slops on the cutouts too sudden a transition to lowest points. It should or could have been much more gradual.
After all the taping work and doing a repair I decided to cut it out. This took many days as I was very careful and the last pic is 18 days later all ready to go again.
Foam for the floor had to be made and brouht in from China so I was in for at least a months delay.
I am committed to the best work I can do without going overboard. This time self imposed quality control required I redo this part. I'm happy with the decision and will do the next floor with alterations.
In the mean time I went on with other tasks and now have the rear seat sump and fuel system roughed out in my head having studied lots of options.
