First batch of doors are now installed. I ran into a little hiccup but I think I will be able to work around it. When I designed the cabinet carcasses, I chose a 2" faceframe because that seemed aesthetically pleasing. At the time, I didn't know what I would do for doors. Flash forward to when I calculated door sizing, I arbitrarily decided to make the doors overlap the openings in the faceframe by 1/2" all the way around. So when I have two doors side by side, that leaves me with only 1" of real estate for two pairs of hinges. When I ordered hinges, I didn't think about this fact and the hinges actually are about 5/8" wide.
The solution to this problem is that I thankfully don't have an entire wall of cabinets like this. I pushed the center doors as close together as I could and centered them but I have an extra 1/8" on each side that I now have to deal with. When I go to install the set of doors on either side of these doors, they no longer will overlap evenly in the openings though they will have an overlap and it won't be noticeable until you actually open the door and maybe study things for awhile. Because the next set of doors on either side of these center doors are the last doors, any extra space I didn't count on can be consumed by the 2" faceframe up against the walls. Instead of the 1" margin I envisioned in my head, it will be closer to 1/2". If I could do things over, I would have chose 1/4" for an overlap and things would have been cherry.
Anyway, the project is finally coming to a close as soon as this second batch of doors is complete. I can't wait to move onto the next item of my honey-do list.
