Finally the PW1127G engines for the A320 are done!
It has taken me a very, very long time. As they were made totally scratch built, I had to make five molds for each stage of creation as I could not go back in case of messing up the master part, no undo button.
The molding has also been a little headache as the easiest way was to separate the cowling into two, but that presented the problem to perfectly match both halves and it was really difficult to achieve this in such round engine.
Finally I choose to cast the whole engine as one part, and made one of the most complex molds I ever had to make. This will avoid having to match both halves, the need to use putty in such process and to avoid modifying the shape of the round engine by accident while sanding the putty for the union.
The Neo engines will go now through the preparation process as instructions have to be designed and later the first units will be made.
But prior that, I will fine tune the photo etch (for example, make the engine’s sharklets to have a curved base to fit on the curved engine).
I will also be making a Lufthansa finished version of these engines with the included decal set.
Recently I have been told that the sharklets that I made alongside the Neo engines were incorrect, short, curvy etc. So I decided to take a look into it a bit deeper and I made a new pair of sharklets.
I have carefully taken a look at Airbus measurements, drawings, profile pictures etc, and I tried my best to make those as accurate as possible, so I saved several profile pictures and I vector-draw the main sharklet shape, afterwards, I reduced the dimensions to scale and made the sharklet shape, guiding myself with a profiled-shaped wood block.
This time, the sharklets have an edge mark, so that it can be easier to paint or in the case of our livery decals, to apply them on top more precisely.
