Ahhhh, the dreaded cross-legged jamb. I posted a similar concern here a
while back (you can search for it in google groups). One of the worst
answers I got was to hit the sole plate with a sledge hammer to plumb the
wall. The best one I got was to shim the drywall outward so that the trim
will sit flush. Do not hang the door unlevel. The doors wont fit right and
certainly won't operate the best they can. Another solution if you don't
want to shim the drywall out, is install the jamb level, trim the jamb on
the side it will be out on, and then, cut out the drywall on the other side
as wide as the casing will be. Try to plan so the trimmed side will be the
one not in full view. Hope this helps.

Have a bit of a problem....I am planning to hang French type doors in
between old area of home and new addition. Plan to make door jam myself as
cost of pre-hung doors was quite high. Have purchased all materials and
just
beginning project. here is problem I have run into....I just now was
checking the level of the wall, and it is off level about 1/2 inch....the
wall leans out at the top, and the doors will open in. no other problems
that I can see. not sure what to do..I have to hang the doors level, so
should I just split difference and be off 1/4 inch at top and bottom? I
could remove plaster from inside area, and put in some furring strips to
level, then drywall. but then door opening would 1/2 inch wider at the
top.
and I am not sure but guess I would have to cut door jam in same fashion,
the side pieces . If I try to leave the way it is the trim will look odd
I
think...couple other things-the floors is level and wall thickness is odd
size - 6 1/4 inch. I am using solid oak 1/2" X 8" X 8' which am thinking
to
cut and attach 3/4" plywood strips the same size - using 1/2 inch oak to
keep cost down. any ideas?
