Well I am pretty sure I messed up for the last time (no more thinking I can do wood working).
A neighbor wanted a cabinet made to match another one in her bath room. She had an old shower removed and sheet rocked. I went and measured the opening twice and made two cases to fill the space. I measured the opening at the bottom in the middle and at the top, they all were the same. I built the two cases to fit into the space minus an 1/8th inch. When I got done with the cases I cut a 3/4 inch piece of plywood 4 inches wide to the opening of the space. I moved it around to make sure I had clearance, and figured out the sheetrock/ wall bowed in and out so the test piece didn't fit. I had to make another case 1/2 inch smaller to fit. With that done I moved on to making the doors. Raised panel to match.
Now on to my bigger problem. I searched all over the place to figure out how thick the panel should be. I fond the answer was 5/8th because I am not running a back cutter. I measured the opening to see how big the door needed to be. I cut the rails and styles to make sure they were correct at 3/4 of an inch thick. I went to the router table set up the bits cut all the rails and styles every thing fits perfect. I was impressed with my self. That is when I noticed I messed up.
I did not leave enough material on the inside of the rail and style it is only an 1/8th of an inch. So when I put the panel in the back of the door only has an 1/8th instead of a 1/4. Can I save the rail and styles? They are made out of birch also the panel is made from birch.
I need to install these today because she has company coming this weekend and wants it done. These will be painted in a few weeks.

I decided to just remake the rail and styles. I figure with the humidity in a bathroom it would just be better.
