I am making some built in cabinets (10 total) out of birch plywood with poplar face frames. Everything will be painted. I attached the face frames to the cabinets with nails and glue but made the frames a bit too large and intended to trim them to fit. At first I was thinking of doing it with a router and then hitting the last few inches with a hand plane. Now I'm thinking maybe I could just use a belt sander or maybe just a hand plane to take off the 1/16 to 1/8" overlap. Any ideas? What is the usual way that cabinet makers do this?
This is my first project after about a 20 year hiatus so my skills are not that sharp. Any ideas or thoughts are greatly appreciated!
