Doh! I’m such a twit…I’ve been wondering how Bruce Hirst created those great wrought iron gates etc. Of course all I need to do it take some green stuff, sculpt *one* wrought iron paling of reasonable length, press mold that with Klean Klay and then cast a whole slew of them using resin and the temporary Klean Klay mold. You then take your resin palings and sculpt a nice gate or grill… which you then RTV mold and cast entire grills/gates with resin.
Simple! I can’t believe I was thinking of messing around with plastic rod!
