Howdy folks. I was hoping to get some good advice as to the best way to assemble some faux beams I'm going to use in my basement. I will be using four of these "beams" spread evenly across the ceiling, and each will have three 3" can lights installed in them. I'm committed to using 3/4" MDF to construct the beams (already purchased material), as we will eventually be painting them, and want a smooth surface.
My question is, what would be the best way to assemble the beams? I was originally thing about using biscuits and glue along the lengths of the 45 degree miters. Would the biscuits and glue be strong enough, or should I consider some other way?
I already know how I will affix the "U" shaped beams to the ceiling, so that shouldn't be an issue. I've attached a Sketch'ed Up drawing of one of the beams. As you can see, they will be almost 12' long when completed, but each whole beam will be made up of two equal lengths of "U" beams.
Thanks very much for any help you can give me!!
