Hello everyone,
Does any body have an idea of how to go through with building a concrete barrier , like those you see on the freeway ??? I've tried searching for these but no results ... Can somebody give me a clue as how to scratch build this thing??

I would say that you would get the best result from casting them in plaSter. I've seen somewhere that you can make moulds from ticker paper. You simple make a shape on your computer print it anfd fold it to the shape you like

Wow! Thanks jakob, I never thought of making them this way..... All my problems solved , for now anyway I was trying to figure out the dragon teeth barriers to

That idea of using folded sand paper forms looks worthy of trying. I too have bought the Accurate Armour barriers, and was going to reproduce more by pressing them into green sand and pouring plaster into the depressions, but this method looks to be a good alternative.

Glad i could help !
