what do you mean it's not combining?
you just select the meshes, and hit the button on the shelf or Mesh > Combine
are you getting errors? what is the error? you can only combine two polygon meshes
when you combine the pieces of geometry will act as one, the pivot point will be at the origin of the scene (so you'll probably want to move that if that's not where you want it to be) and stuff happens in your outliner and hypergraph
that's a "Ch" pronounced as a "K"
