cabinet making is NOT easy unless you know what you are doing AND have all the right tools.
i know most about face frame cabinets, and could make them still, not having dont it in over 10 years lol.
i could never scribe to the wall well though.
for face frame cabinets, make the sides, the back is bare, with a rail across the top... in the middle you have to space the "walls" at the exact distance for the doors to go between (calculating the face frame width, and the center rail width).
like this: |_|_|
lets say you are going to make 14 3/8" width doors... thats 28 3/4 space for the doors you need. if the face frame rails on the hinge sides are 2 3/4" in the middle 2" on the ends, then you need to make the center wall 31" from the end wall. there will be a 1 1/4" overhang of the FF on the end, 1" overhand on either side in the middle.
that is for doors with no center support where they meet. that is also for flush mount doors with hidden hinges. if you want the doors to be outside the frame (a more usual application) you need to know the needed overhang for the hinges you will be using. then you must subtract that times 2 for the distance between the rails.
if you are adding a center support brace, you must figure the total door overhang, the subtract that, after adding the width of the center FF brace.
also, unless you an expert with biscuts / dowels, making the face frame is going to be a MAJOR *****.
all this for 1 simple 4 door cabinet with a "wall" between the sections.
to be honest, with NO disrespect intended, i always chuckle when people plan on making their own cabinets, unless they truly know what they are doing. i have seen many many try it, only to break down and buy cabinets later.
if you are serious, look into a book on face frame cabinet making, read it thoroughlly and make sure you understand it all before going buying wood, and stuff.
