How can I weld a rotating part to a Character's Right Hand? (R15)

I tried Welding a part that rotates, to the Character's Right Hand, and the result I got was me attached to the part, unable to move.

I'm trying to have this above my hand, and stay there while I'm moving, basically. It's fine if it doesn't need to rotate, It never seems to stay above there, but go inside of the arm.

I did this down below to try and make it go above the arm, yet it keeps staying inside of it.

plr.Character.RightHand.Position + Vector3.new(0,1.3,0)

-- plr is defined as :

 local plr = game.Players.LocalPlayer
