[This is part of my How to Install Crown Molding series.]
It’s been a long time since a professional finish carpenter submitted his work to The Joy of Moldings. And what you are looking at here is the work of just such a pro. His name is Michael Stiller, and he’s under the employ of a general contractor who values fine craftsmanship and excellent design.
If you’ve ever read my posts on how I feel about backlit crown molding in residential homes, then you are about to watch me humbly retreat from my previous stance. Because looking at Michael’s finished design has made me a believer that a lighted crown molding can be a beautiful addition to a properly designed great room.
The design aspect in this room that makes a believer out of me is the room’s geometry. Lighted like it is, it reminds me of the facets of a diamond.
My hat’s off to you, Michael and your employer, for showing us what a properly designed, backlit crown molding combined with superb craftsmanship can do for a great room.
I discovered your blog after my employer mocked up a four-piece crown on a barrel vaulted ceiling, and expressed that it would have a light installed behind it.
I had no clue at the time how I was going to support the upper crown. I feared the crown — without substantial framing — would twist or cup over time as one side of the crown would be heated by the lights and the opposite side would remain cool.
So I went to Google search, looking to see if anyone had worked on such a task, which is how I found your blog.
The spring angle on the crown molding is 45 degrees. I broke up the install by installing the lower half of the crown molding first, to make it structural, so I could use it as a barring for my upper crown.
I installed an LSL ledger (an engineered lumber) because it won’t shrink. The lower crown is screwed to the wall studs and to the ledger and the lower crown.
I made 12″ blocks using LSL and plywood that are glued together with yellow glue. I then Installed the blocks every 32″ on center by glueing the block to the 1″X 6″ and screwing up through the lower crown into the blocking.
When I installed the upper crown, I applied PL premium glue to the entire surface of the plywood blocking.
To make a long story short, after the glue set I could hang off the crown. It was rock solid.
