Ok, so I decided to build some hanging bookcases for my basement;
hanging, since a desktop will soon (!) be constructed below it.
The cabinets are made of 3/4" maple plywood, 24" wide, 31" high, and
11 3/4" deep, all outside measurements. There will be 6 of them
across the wall, with a 30" (or so, not sure yet) floor standing
bookcase that will match the other book cases in height.
Bookcases are standard box construction, biscuit joined with a
faceframe to be applied after they're mounted. The back has a groove
deep enough for a 1/4" back and a 3/4" 45 degree plywood hanger. The
matching 45 degree hanger is of course screwed to the wall studs.
The problem is this: there is a section of the wall that bows out
about 1/4" to 3/8" of an inch that causes the cabinets to not sit
properly square to the wall. Since the cabinets are 10 3/4" deep,
this leads to a gap between the cabinets at the front edge, where the
face frame will be placed. In fact, as I look at it now, there's a
1/4" gap between two cabinets.
I was planning on overlapping the cabinet fronts by 1/4" on each edge
with the face frame (this would make 3/4" + 3/4" + 1/2" = 2" face
frame) which would cover the gap, but since the cabinets are not
square, there will be a gap if you look at the cabinets closely, since
the face frame will not sit flush with the front of both cabinets that
are butted together.
I also wanted to screw the cabinets to each other (more strength), and
to the wall. Tough to screw the cabinets together when they're not
butted tight together!
So, what can I do to fix this? Near as I can tell, the only thing
that I can do is to shim out the wall mount bracket until it's flat
(which could get ugly, as it's a 15' wall). I would also have to shim
the bottom of the cabinets to keep them plumb, but that's not a big
deal as I was planning on putting in under-shelf lighting - any gaps
created by plumbing the cabinets would be hidden by the box built
around the lights.
What do you think? Good? Bad? Or, so you have another solution?
