Aight, we are finally getting a little closer. I had stained the door and put some clear on it Monday night. Yesterday right when I got home I put the glass in the door and caulked it up to hold it in and to seal it. The caulk in the picture dries clear and won't stay the white color that you see.
I had a handle that I bought for it about 3 months ago that I also installed on the door. I may have to go back later and recess the screws that you see in the pictures, not sure if it is going to interfere with the seal.
I waited a few hours for the caulk to set up and start drying. I then installed the door onto the cabinet. Worked like a charm. I had two different weatherstripping that I was able to snag from work. The first one was a D style seal and was a little taller. After I installed it the door wouldn't close all the way because it was too thick by the hinges, so I had to pull it off and go with the thinner grey flat seal. Not 100% sure it is going to hold humidity properly, but I figured I would give it a go.
The door seems to close well and it seems to push air out when it's closed, so I think it may work. I snapped a couple of quick photos, pulled out the bottom drawer and replaced it with a glass of water. Added a large humidifier in it from my cooler, dropped in the hygro and start the waiting game to see if I need to make any adjustments.
It was stable when I went to bed at 55% and when I checked this morning it was at 56%... so not sure if it started moving up or if it was just on the verge before. Can't wait to check it when I get home!!
