I'm bidding on a job that will be a wall unit with open shelving made up of 2" thick panels. The panels are hollow to run wiring and house puck lights at the bottom of the fixed shelves. This will be a very straight contemporary design, painted, with both fixed and adjustable shelves.
How are the 2" thick hollow panels typically made up for this type of design? I would prefer to use plywood instead of MDF if possible for weight reasons.
From contributor K:
If you are talking about the shelves... torsion box. If you are talking about the carcass... think of a hollow-core door, but make sure you have solid wood where the shelving standards/pegs are located for strength.
Carcass was a different story. One big face frame, 3 boxes pocket screwed where possible to face frame. Where not possible to pocket, I glued, clamped and attached cabinet sides to adjacent sides using trim head screws hidden in shelf pin holes. No lights in this one, but I've done them on other ones.
