I spent lots of time studying the plans for how the baffles are to be trimmed. The pieces in the kit are very oversized and their shape confused me. I had to seek some advice from the Van's Airforce Facebook page. I then was able to understad what the finished product should be. The forward ramps have been trimmed and bent.The side baffles have also been trimmed and the bottom tabs bent. I was then able to move on to the conicle bend. The plans say to "lay out the pattern on a oversize piece of .032 sheet. You can't get enough leverage to make the bend on after you cut the pattern.
