Bulkhead material/Thickness for drumspinner/beater/vertical discs

[Runsler]

Sadly i think hardox outer armor might get way too heavy for my design, except i'd make it really, really thin
Maybe if i just have a really thin plastic inner chassis, and fixing top/bottom plate with nutstrips or stuff like that. But with additional aluminium bulkheads that wouldn't leave much weight for the weapon itself.

Already was thinking about mixing some materials, but weight is always an issue, and i'd have no idea how i should bolt a relatively thin outer layer of metal into a thicker plate of plastic without screws sticking out (and being an easy target for horizontal spinners) or cutting screw heads so far they don't hold anything anymore.
Possibly with wielding the screws right on the metal, drilling holes into the plastic and fixing them with nuts from the inside afterwards. But that seems so crude, and my wielding skills are quiet non-existent.


Do you have pictures of TS3?
Also, how did the Nylon shatter? I only know Nylon used for stuff where it's really flexible and wouldn't shatter at all. But then again, i only know Nylon for stuff where it's used really differently.

Edit:
oh wow, even 25mm HDPE? for all the side or just for the bulkheads to reinforce them?
was planning with 20mm by now.
Could i just put 20mm HDPE as side armor, and put a second plate on the inside of that to strenghten the bulkheads where needed? or wouldn't that be any useful and i should better try and make everything 25mm? With everything 25mm, it's just as heavy as taking 3,2mm hardox.
Harder to work with, but maybe worth just taking hardox for everything, then.
