Hi,

I'm a woodworker and I got this job to make a frame/shadowbox for a very large piece of art. I have a concept of how to do it but certain details worry me.

The specs are:

  • red oak frame
  • 2.5" deep
  • 3/4" wide
  • 102" tall x 54" wide
  • 6mm di-bond backing (aluminum veneer with foam core) very rigid and light.



My plan consists of creating an L in oak where the plexi/acrylic will be captured between the small leg of the L and a filler piece, more or less a 3/8" lip. The dibond after the filler and a 3/4 pine structure for support and serve as the french cleats for mounting.

My question, is 1/8 plexi going to sag or should I go with 3/16"? 1/4 i feel might be too heavy but I'm open to suggestions.

attached are some images of my concept in SketchUp.NEAR ART 3 side view.jpgNEAR ART 3.jpg
