Then things got intense and much plywood was cut to fit, while not many, if any, photos were taken. I must have been enjoying the build process too much.
Repeating the process of scoring and folding, 1/32" ply slivers were bonded in the gaps between the flat panels. These took up the space better than filler alone would do. Re-enforced with cyano glue and zapped with activator, they were then ready for sanding. I use a flat Permagrit file for this work. making sure not to sand straight through the plywood!
Once sanded to a decent profile, the whole lot was then fillered with a one part, air drying filler and left to go hard.
Once sanded down, a handy comparison with the original cardboard mock up was in order.
