Today I learned that Polycarbonat does not like to get bent with a heat gun
First I started with drawing:





The diffuser was the first part I wanted to shape. Therefore I put the sheet between two large tubes and cared that it couldn't move in the process. This first step went pretty well, even though it wasn't easy to adjust the angle. Then I wanted to bend the first air channel and disaster striked. I have to add that for this step I pressed the sheet between two flat wooden boards to prevent unwanted areas to bend. With the heat gun I worked on the air dam until it had the right angle. The I took the sheet out and it wasn't flat anymore The whole sheet was tweaked... So the heat gun was no good idea.

Ok, so I will go back to the way I built the first undertray (no my oven is to small to bake the sheet in it and it is for food only ), but first I have to visit the hardware store, again
