Last pictures of the vacuum bagging.

I did need better plastic to prevent leakage.

The extra pressure vessel to get a smooth working pump, it lowers the frequency of switching.

Pressure during the first hour -0,5 bar, equivalent on 200 kg / 440 pound on my two little doublers, second hour -0,35 bar, last hour 6 pinholes on the bag around the plywood doublers to remove the moisture.
Last picture gluing the motor mounts against the fuselage side. In mirror image to check the alignment.
Near the engine room I use epoxy 2 comp. Near the tank compartment white wood glue.
