I find it difficult to believe that you're going to all this trouble, and even pressed out the axle, yet you're further weakening an already proven to be inadequate axle, and putting it back in the motor instead of replacing it with a larger stronger axle with more room for the things you want to run through it. The only other change would be going to bearings with a larger ID.
I still always appreciate pros and cons about any idea i have and you are always the one that is more critic about these idea.
That make me thing a bit more about these so i like that as well.
The axel are innadequate for poople who dont understand how torque work on metal part... if you use a little bit of mechanical engineering it's easy to know how to use it without having problem.
Remember i have 5 X5 motor and am also one of the person who have put the most kW into them and torture test them more than enough... and... i NEVER had any failure... ( i have all existing generation of X5 too)
I never twisted any axel and i doubt i could have problem doing it. The torque arm i make are also a good match to avoid any metal torsion or shear.
I will put back teh axel with the DP420 epoxy wich will be very strong so the stator wont turn on the axel.
The idea of making a new axel would cost me $$$ and i dont have any source for having a custom made axel for cheap. So i have to keep the original axel
I abandoned the idea of cooper tube and will concentrate on the aluminum disk that take the 6 cavity in sandwich.
I already machined the two disk and the stator border seat to fit them
I will use the epoxy DP420 too to fix them
