I never got a good look at the real dome, but I've seen several on carbon copy ecto's, so I don't know if they're real. So far as in the arrow, you could either build it out of wood, or for something stronger, use some 1/2" maybe 3/4" or 1" square channel steel and weld it, then for the arrow, just heat up the end and shape it or get a little creative by adding some corners from your square channel steel, it'd be much more tougher than wood, and wouldn't rot as quick as even painted wood would. Just some suggestions/questions.
