Here's your bug report :P

Basically, bullets and custom parts can't be crafted yo!

Tried to add bullets to the benches in V15.6.0, but got crashes because bullets don't have any models. Might need to enforce the 3D bullet system after all. Bleck...

Bullets are now craft-able in V15.8.0.

Will get to it when I can. Either with a bullet-specific bench or using the one for the guns. Probably the one for the guns given the lack of guns in the mod.

Not sure yet about the decor bench.
