Weldable moving brushes?

Garry's Mod mapping
#1

All right, I’m trying to build some sort of stow-away weapon racks using func_doors in a couple rooms of my map, and I’d like to mount some weapons on them (In Hammer would be nice, but I’d settle for in GMod).

When I go to weld an object to it, however, it doesn’t register as something that can have a physical constraint put on it. An object’s silhouette will appear on (often in) the func_door, but I can’t complete the weld/axis/ball joint.

I’ve also tried with elevators, same deal.

Any ideas?

Uhh, curiously, the gmod_allowphysgun 0 worked fine, glad I learned that one, but the gmod_allowtools didn’t change them.
