They are using a saw for some purpose. Anyway, I find the sounds annoying. I would suggest, delete them or change to something else.
Would they be less annoying if they were lowered volume, and maybe less noticeable? (for example the dragging and clang of some metal object is pretty noticeable) Maybe include some muffled voices, or medium-distance airplane flyby, maybe a truck or jeep driving past the hangar?
Best option I think would be to have the volume for this effect settable by the player.
I wonder where the soundpack guys went? Mitsu, TwinBoom, Ranger, and I'm sure I'm forgetting somebody great.
