Enough already with the laying around the house. After dealing with the flu for eight days, I got back to work on the crown molding project for my dining room. I had cut four of the ceiling beams to final size the day before I got sick. These are the beams that run left to right across the room. The next step was to begin fabricating a lap joint on each end of these beams.
In my last post, I was contemplating how best to make this lap joint. In the comments, Duane suggested a simple router jig, which I was not wanting to do because of all the repeated passes I would have to make. The largest straight bit I have is 1/2 inch and the width of the lap joint is six inches, so that meant 12 passes to complete the lap joint. Plus, as I began cutting away the material, I decided to make each pass with two cuts: one at 3/16 inch deep and a final pass at 3/8 inch. So, in total, making this lap joint took 24 passes and each board has a lap joint at each end – a lot of cutting. A radial arm saw with a dado blade would be the best way to do this, but I don’t have such a saw, so the router is the next best tool. I made a simple jig as Duane suggested and made the lap joint.
After a little sanding with my new Makita 5″ sander (love this tool – just wish my old Porter Cable had worn out sooner) I painted on a coat of primer on the beams, then filled a few imperfections. Then it was time to attach them to the ceiling.
I reached my goal: these four beams are in place before supper. I still have to fill the screw holes and then do this all over again for the two beams that run front to back (see the SketchUp illustration of the beams by clicking here). I hope to have the whole simulated beam part of this project completed by this time next Sunday. Then it will be on to the actual crown molding. Yes!
