The buider I'm doing trim for is installing split-jamb doors and will not be talked out of it. Anybody have any tricks or comments to make my life easier and to assure a well hung and operating split-jamb door? I'd just as soon do without them but shimming and hanging is going to be a pain with no access behind casing. I was thinking of removing the casing on the hinge side ,shimming, then reapply the casing. Either way it is more work for me. Thanks.
