Step 5: Test It Out / Patch Up the Wall
After countless cycles of testing and tweaking the door operation with the wall open for a month or two, I finally felt comfortable closing up the wall. Here you can see some of the new drywall starting to go back up.
From there it was just a matter of painting the wall, and it was back to looking stock. I purchased a blank white wall plate from Home Depot. I drilled it out for an illuminated pushbutton and a 3-position keyswitch, both of which I bought from McMaster. I also purchased a plastic hatch door from McMaster for the control box. Lastly, I added an air conditioning vent above the door. This lets the air venting noises be heard, and it also provides me access to the valve and pistons should anything go wrong.
After you've tested the door and patched up the wall, that's about it! Good luck with your project and feel free to post comments and ask questions if I skipped over anything you might need help with. Thanks for reading!
