Hello and good week start for all.
Back, I was reviewing and turning the whole front of the He, analyzing what could be the best repairs, without hurting too much the pieces ...
In the case of the repair # 3, I remembered that the union of the transparent parts with the fuselage I did with Tamiya ETC, but between the transparent parts I did it with MKK. With a thin and wet paintbrush, I passed it over that upper union until it became smooth and with a pair of tweezers, I managed to carefully press the end of that union, I could see that both pieces fit correctly. Then I cleaned all that union very well and applied ETC:
Afterwards, I filed and removed the rails of the roof window (# 1), as well as a rear hatch, then pass sandpaper to soften as much as possible that part.
That gate that I sanded, I can replace it with a square of styrene.
What I could observe is that the "step" (# 2), is likely to be resolved with putty all along that union, from the same union and up to 1 or 1.5 cms., backwards, then with only sanding, make that step disappear as best as possible ...
Then it will be just a matter of replacing the lines of rivets, panels and that hatch.
Having no need to detach the bubble, for the composure of # 5, only with jewelry files was thinning the piece of plastic to reach the level of the transparent piece ...
It seems that these "defects in the joints", were acceptably resolved ... without the risk of having to detach the pieces and lose part of the joints that were clean and without problems.
After the application of putty in all the required parts, I´ll give them the drying time and do the sanding work with due care, you will probably I have to replace some of the masked windows that could have been affected.
But that will be until I see the results.
