Inside works under the hull upside-down
All joint surfaces or edges have to be glued to each other. The sheets of hull to the bulkheads and the cleats, and to the backbone in addition to to the stringers or the bulkhead doublers also.
Before continuing the second layer of the radius skin, I have to do a lot of things inside, especially the gluing of the junction. Waterproof (in one direction) covers for avoiding moisture condensation to the surface before winter is coming.
Gluing the fillets on the junction of the perpendicular surfaces inside under the hull (upside down) is quite a boring work to do. Lots of work without spectacular result. Filling of the screw head holes (outside of the hull) is a little bit more boring activity. Sanding the surplus glue material from the skin – it is a forsooth man-sized task; in addition to the winter is coming, this way the tools and equipment must be covered for prevent them against the moisture condensation.(rust). And I didn’t mention the temperature. Below 18°C if the relative moisture content is higher than 60% it is a challenge to glue. You can try it, but no there is no way to get proper result. Therefore, I heated the stove from 0°C to 20°C.
An insulated and conditioned hangar could have made my work much more productive.
