The biggest problem is the light, it shouldnt get hot. So it needs to be not a bright light.
Then maybe using Leds?
I think this thing is made out of steel, then painted black, then red
And then sanded down to the steel.
So this guy get this weathering effect, wich i dont like in case.
I like new and shiny looking props, so i would built it new and shiny,
maybe with a little bit weathering.
Also the hand with the light needs to be a bit moveable.
Tomorrow my school holidays begining, so i have much time.
Im pretty sure to built a few of these, there just need to be enough interessest for this.
