I agree with Dan Schaefer ... hang in there. I too have felt the pressure from the NIH syndrome but will continue to invent as I go along. I recently created a robust method to attach cowling w/o relying on piano hinges. The lower cowl will be removable with only 8 hex head counter sunk screws. The top cowl sides will have about 6-8 screws each side. Over the top of the firewall ... no mechanical fasteners at all. I have plenty of building to go before all of this gels so please be patient. I have no pictures and no hard copy plans to share at this time. This is for my RV7A but the problems/solutions are about the same. A mentionable feature is that the screws will be counter sunk into phenolic rod pieces about 3/8" long. These are bonded into the cowl. The screws nest in this armored piece and attach to nutplates. The heartache of glass wearing under the screw head will disappear with this creation. So John, we need richly endowed creative builders and it's apparent you are very blessed with creativity. You have a very small problem to solve to isolate the loss of ram out through the filter. It could be done with something similar to a large ball valve cut in 1/2. Of course it would have to be light weight and possibly of sheet metal. The 1/2 ball valve side could block off one side of the filter and a 1/2 sleeve could block off the other half, together they create a sleeve for ram air. When filtering is desired the ball is rotated to block ram and open the side of the filter. The other side of the filter allows a pathway around the 1/2 sleeve and into the induction. Thanks for sharing your filter system and I feel you'll serve-up a solution. We RV builders need this filtering system too. I would use it. Best regards ...
