Try using 100/300/250/10 recipe. I use this recently in hope for 46cm gun but manage to get around 5 turbines in progress. (Flagship : Haruna Kai, HQ level 84)

BUT, be aware that it may take a long time to get one. Take it easy and just craft them for dailies quest and you will get one eventually.
