Thank you yellowvert for trying this and it being succesful and blacksix for the idea and sirLotus for help. Then also documenting and sharing with us.
On pic 1 there's the solid alum panel thats held by the 4 rivets.
If one was to cut the opening smaller; an area within the 4 rivets just along the perforated air holes in pic 3, then maybe the solid alum panel can just be riveted back in place, or use some type of screw/bolt for easier access in the future? Then discard the piece with ventilated holes? Is this possible, and any harm in discarding the cut out piece with perforactions
You make a good point. Had I cut in enough to allow me to use the same size panel, it probably would have been enough to allow one to re-rivet in the perf panel and then maybe add some small aluminum trim to clean it up. I will tell you that when you are standing on your head trying to get one hand back there (and then add a second little person later on to help crimp), the more space the better. But cutting it 1/2 on each side wouldn't have mattered. I think cutting it 1/2 on top and bottom WOULD have mattered. Again, in retrospect, cutting just a little less off top and bottom might work.
Sorry, thinking as going...if you cut it narrower (less off sides) you could re-rivet. I'd generally stick with all the height possible because you would need to add the trim on all 4 sides. I just don't think its reasonable to think you could cut it so clean and straight that you wouldn't notice. Lord knows I didn't but I realized instantly that that wasn't something I could do. Maybe wrong tool?
