Bent laminate plywood banquette
I'm looking for a bit of a reality check.
I'm planning a semicircular booth. For the seat back, I was planning on glue laminating, using 2 layers of 1/4" birch plywood followed by one layer of 1/4" alder. The radius is 4'. Below the seat, the radius is about 2 1/2'. I am now thinking that maybe three layers of birch followed by 1/8" MDF and then alder veneer would be better.
For a frame, I am using 3/4" plywood as a template for the seat, back and kick plate. For the seat back, the lamination would span about 1'-2" (see attached - I hope)
Couple of questions.
I find conflicting information of whether or not I can dry bend 1/4" birch to those radii. Only the seat back holds any weight (when people lean back.)
Secondly, which method would you use, or would you do something different?
