Trimming a deep passageway between rooms.


My wife wants my to dress up the passageway between the dining room and living room that is about 18.5 inches deep and 98 inches wide. I want to put wood on the sides and then trim around it like a doorway. The problem is I can't seem to find nice wood that is 18.5 inches wide other than plywood which I want to avoid if at all possible. I see nice select quality pine and poplar at Lowes, etc up to 12 inches wide. Lowes did have a 20 inch wide pine board that was basically a bunch of smaller strips glued together but it did not look as nice as the select pine/poplar as it had a lot of knots. I just want to paint all the trim white and not stain it. Would it be that hard to cut two pieces of the select grade wood and then try to make it look reasonably like one piece after being painted? I have a table saw [Ryobi BT3100] so I could rip the pieces at 45 degrees and plane/sand edges, glue and nail the joint so that it is on a stud, then fill it with something and sand. Should that look OK? If so what should I use to fill/hide the joint? I suppose I could use the 20 inch wide stuff from Lowes but it would be much easier working with the smaller select quality lumber that also looked much nicer. Thanks for any help. --- Steve

You need a quick lesson in woodworking.
Lesson one: wood over 12" wide is almost impossible to find and if you do, it can be very expensive.
Given the fact that you are going to paint it, I'd not use real wood at all, but instead, use MDF. It will be flatter, smoother, need no sanding, be stable with climatic changes, and no one will know it is not real wood. You can trim it with wood or other trims that are available according to your tastes.
Next alternative is to glue up narrow boards. This is done all the time and has benefits over a wide boards. Narrow glue ups will often be more stable and less likely to cup or warp. Fine furniture is done that way. Just look at a table top or dresser. You'll need a bunch of clamps and a flat surface to hold everything until the glue dries. You can do it on the floor, on a bench top, whatever works for you. A thin coating of glue, clamp, let it set, trim to final size. You'll need at least 4 or 5 clamps on an 8' board.
Many of us use biscuits to help with alignment, especially on long boards. You need a plate joiner or router with the right bit to make the slots. I recommend that method. Doing this as a glued board is easier than doing the 45 degree cuts and nailing you are considering. A good joint will be hidden under the paint.
What would I do? I have plenty of tools, clamps, plate joiner, sanders etc, but I'd use MDF just ripped to size.

Thanks for that info Edwin - very helpful. I never though about or have tried gluing my own boards but it certainly sounds like something I may attempt. Would you suggest that I use two 10 inch wide boards or use smaller yet? I will also look into the MDF. --- Steve

Do you already have the clamps in needed length and quantity? I'll echo MDF is easier and already in required width & length.

No I do not have clamps yet. I was at Menards yesterday and saw that they had 4X8 sheets of 1/2 inch MDF for $15. MDF never even crossed my mind until I posted in this newsgroup. I also noticed they had a lot of prefinished molding and door jambs made from MDF. Thanks to everyone for the advice on MDF as that is what I am going to do. The cost savings will also be very significant and I can rent a truck from the local store for $19 to get a couple sheets home. I will cut the sheets in half with my circular saw or have them do it at the store and then rip to spec on my table saw. Hopefully my 36 tooth Freud blade will do a good job and I can sand edge for final finish. --- Steve

You would have to glue up a panel from narrower boards to get the 18" panel. Otherwise you will get problems with warping.
Since you are going to paint it I would use plywood or mdf.
You should be able to find veneered plywood that would also be an option.
If you are doing an existing wall you should need 1/4" ply only.

Thanks for that info. I think I will try gluing some narrow boards or using MDF. --- Steve

Was this wide board not straight, or too much filling/sanding? I have a picture of a similar " archway", the arch is done in strips of beadboard or beaded panelling with moulding on the ends, which looks pretty good. I'm doing a couple 7" ones right now in my post and beam home, so I'm making the top look like a beam over the doorway, the beams there now will be covered up as they are only 3" and offset, and have small damage.

The wide board did not look near as nice for the cost and then there is the problem getting it home. I can haul smaller boards in the car. Thanks. --- Steve

Sounds like a great opportunity to do some raised panels.
