Recently completed a kitchen where the upper cabinet did not spec out a divider system though it was clear one would be required. The idea was that the client would choose from a selection of Hafele or Rev-a-Shelf or other system. After reviewing manufactured alternatives, the client asked if I could design something that would handle the "dividing" as well as make additional efficient use of the cabinet. The cabinet is quite tall (33") so there could easily be storage on top of the dividers. Possibly more than one shelf though I show just one.
This is what I came up with this morning in Sketchup. Idea would be to dado a top and bottom to accept 1/4" baltic birch with radiused edges. Top would be a shelf for large baking bins, and the dividers would be sized for flexibility. Thinking 3/4" baltic birch all sprayed before assembly with waterborne conversion varnish. One of the requests was to have the lower platform protrude a bit so that it functioned as a drop and skid zone for the heavier objects. The paint is getting damaged on the front of the face-frame from "dropping" heavier objects as they're lifted with one hand. The design shown has a 1-1/2" lip (both directions) but I'm thinking just a 3/4" thick lip protruding to the front of the cabinet (just behind the face-frame). The setback is required to service the hinges. What I would typically do with slides is make a folded pre-finished side shim ... and perhaps that is what I should do on both sides here as well to protect the doors. That would also make adding shelves up above easier as well, though it would cannibalize some of the space.
Love a review of the approach.
