We put 3/4 inch tongue and groove pine on the walls of our new cabin. Now we want to put up 1 x 4 pine for the door casings. The problem is that the door frames were made to use 1/2 inch wallboard so the tongue and groove stick out too far to make a nice fit. Any suggestions?

Hi Aspen...

You can either use your table saw to RIP some 1/4" stock from a 1"x6"x8' pine board and build out door casings to the 3/4" T&G... OR you can run down to the home depot or Lowe's and purchase some 1/4"x1"x8' flat stock and use that to build out the door casings. Use construction adhesive to hold the 1/4" strips in place while tacking with a few nails and then install the 1"x4" pine trim. Should blend almost seamlessly after painting or staining...;)

You could also use your table saw to cut out the 1/4" from the back of the trim you will be installing... all but 3/4" at one edge that will sit on the door frame. Here, you would cut out 2.75" wide x 1/4" deep piece out of the back of the trim pieces (which leaves 3/4" not removed from the 1"x4"s) and THEN cut length and mitered corners (if having mitered corners). Hope that made sense...

Let me know what you think...

Assuming you are talking about split jams, I'll go along with Mark. Remove the casing from the exterior side of the jam. Not the side to which the hinges are attached, adding to that side will screw up the hinge swing and latch striker. Rip 1/2" strip from 1 X material, fir or white pine preferred. Glue to the edge of the jam. You can glue and shoot a few finish nails to hold extension until the glue dries but you will get a better joint if you build a clamping jig.

That jig would be; lay a 2x4 on a piece of 3x4" plywood, aligned with the edge, flat side down. Lay the jam and the extension material next to it. This is only to space things apart. Nail or screw a second 2x4 to the plywood next to the that. To use the jig, loosely clamp the first 2x4 to the plywood. Tight enough to keep it from popping up and loose enough to let it move. Put film of wood glue on the edge of the jam and the extension material. Place in jig, face of jam up, and clamp the two 2x4's together. Clamp each end and two more clamps in between. Place duct tape in bottom of jig to prevent glue from sticking to plywood. If necessary use shims to make extension material stand a little proud of jam. Let dry for at least 1 hour. Sand extension flush with jam surface. Reattach casing. When painted you will never know it was done.

Should take you about 1 hour per door.
