After several modifications to the A320Neo engine that I started some time ago, I have been able to finish the main shape and thus leaving it ready for next step.
I am currently using drawings and self made drawings as well as reference photos in order to shape this engine as best as possible to match the PW1127G model.
Further steps will be to empty the engine as it is solid now and proceed to make the pylon so that I can shape the rear section of the engine with its cowling pointedly aerodynamic fins (sorry for the not so precise term).
Next photos will show the process with the main base of the pylon and in the meantime, I will study the best options in relation to the engine casting / assembly so that the different parts can join together as best as possible.
