How to attach skeletalMesh to skeletalMesh?

  1. I can attach a static mesh with no problems to my characters hand but how do I attach my custom SkeletalMesh weapon to my skeletalMesh Characters hand. If I try to do it the same way as with Static mesh the ‘attach actor to component’ says the target is incompatible.
    What’s the best way to do it? This weapon will be dropped, picked up etc so a permanent method isn’t viable.
