Hey there. I’m new to this forum and a pretty new woodworker. I am building a couple of large “ceiling clouds” to hang in a music mixing room (my “plan” is attached below).
Each “cloud” is a roughly 8’ x 8’ square frame of 4-1/2” wide 3/4” cherry wood - assembled like the walls of a box, not a picture frame - with mitered corners (how hard can they be? haha)
The bottom of each “box” will be made up of three open frames (each assembled from 6/4 poplar and assembled like a painting canvas frame and covered in fabric) and two 7” wide 3/4” cherry boards alternatingly laid into the bottom of the frame - so frame, board, frame, board, frame. All of these will be screwed to each other and to the frame from the inside.
I’ll add an additional cross bar to help prevent any sagging.
Each top corner will have 2’ x 3’ gussets, flush with the top edge and glued/screwed in from the outside. This entire box will be filled with rigid insulation and hung on the ceiling from pad eye plates screwed into the centers of the gussets.
This seems pretty strong to my inexperienced self and I live in California where the weather fluctuations aren’t extreme, but I’m at a loss as to whether these things will hold together over time. Will expansion/contraction be a problem, especially with the mitered corners?
Thanks for any thoughts on this.
