Is there any way to attach a Cannon to a rotating platform without it fall off due to physics?

I have a rotating platform, and I want to place cannons and turrets on it, but in game, they instantly fall off due to the physics. Is there some way to keep these devices from moving around?

Spawn devices?

Does making them children of the rotating platform do anything ?

I have the cannon “Attatched” to the rotating platform, but no. It still slides off as soon as the game starts

The StaticMeshComponent has a gravity option

Doesnt work, surprisingly. I think that option refers to the spawn pad, not the cannon itself
