Thanks guys , Vaughan the crash moulding for a small part like this couldnt be simpler. I just got a piece of clear acetate (from a chocolate box if i recall , but loads of types of packaging have clear bits on them) , I then got the kit part , stuck it on a wooden stirring stick , then heated the acetate over a candle and when soft enough , pushed the kit part into it . I had several attempts and chose the best one , cutting it out with fine scissors . The beauty of this is that the clear acetate used in packaging is plentiful so it doesnt cost anything to experiment . cheers tony\ said:
