I got the engine compartment bigger top piece done. The piece is curved half of it´s lenght, and I was not sure how it´s going to bend cause it´s 5 mm thick.
I did mill grooves in the underside in the area that should curve to help it bend.
Then I band saw a wood block to the same curvature and place the aluminium piece between them. Next I put it to a hydraulic press and press the wood blocks together (plate between), but as I release the pressure the plate returned straight
Then I decided to heat the aluminium plate hot and did the pressing again. I left it under pressure to cool down, and this time it did stay in correct shape
