OK now we have the inner and outer side of the door,.. thats an easy mold,.. but the frame is tricky ! we want to use a (I dont know the englisch word for it, maybe its the same like in german - a lost core?) out of polystyrol foam ? and we change the shape of this frame... what is the best solution to get this polystyrol core? first an RTV positive mold, then a negativ mold and out of this mold the cores we need? why diddn't we start with a small piece ? or some easy stuff lika a bonnet :/ ok now I was drwaing about 1.5h on this stuff ... good night Edited 12 Years Ago by Bluebull
