Thanks guys.
What I'm trying to bend are the interior panels of a 1/72 Fw190's landing flaps. So the whole this is only about 30mm long, by about 8mm.
It just needs a slight curve, and I'd read that anealing was supposed to make metal less springy, and therefore easier to bend.
Think I'll just go with a length of thin dowl on a soft mat.
Thanks
Karl
