Hasegawa Heinkel He 111 Build in 1/72 Scale Part II

I’ll be modifying this model to H-20 standard, the most obvious difference is the dorsal gun position of the H-20 was replaced with a turret mounting a 13.1 mm gun. Here I have inserted a section of PVC pipe to build up the base for the turret.
The gaps in the opening were filled with superglue and the area smoothed with Mr. Surfacer 500.
The turret ring was fabricated from various bits of Evergreen stock using the ring from a Revell of Germany He 177 kit part as a template.
There is a tricky area on the Hasegawa kit which I have learned to respect from previous builds. The bomb bay at the heart of the aircraft is the junction of seven different parts and the fit is not optimal. There will be noticeable seams here if one is not careful. It is best to address the seams in stages to get the best result. Here you can see the wing to fuselage to bombay joint has been filled using superglue and Mr. Surfacer and smoothed.
For my build the external racks are needed. Test fit these parts carefully, as the backs of these will need trimmed to get the best fit. Gaps at this point are filled with Perfect Plastic Putty and the excess wiped away with a damp swab.
The Eduard canopy mask set is a big time-saver. The kit provides an overhead instrument panel with a decal for the dials but does not have the panel next to the sliding hatch, which is a PE part here. The canopy curtains were made from rolled up sections of masking tape.
Aside from the bomb bay area the rest of the parts fit well. I use MEK from the hardware store which is the equivalent of the various “thin” cements on the market but vastly cheaper. This tends to melt any minor imperfections along the joining surfaces and results in a tight fit.
Here is the canopy in place with the seam filled with Perfect Plastic Putty. The PPP is ideal for this application.
The underside of the canopy join was not as tight as the upper side but close enough to fill with putty.
The other major difference between the H-6 and the H-20 is the H-20 had fewer transparencies in the area of the ventral bathtub. The excess windows were simply sanded smooth. The fit of this clear part is extremely good.
Here the RLM 66 interior color has been sprayed on the exterior of the canopy.
