In my rented apartment, there is a cabinet above the stove which cannot be used for storage – the stove exhaust fan is sitting there. The first photo shows the doors closed with an 18" ruler for scale.
Despite the exhaust system, there is a lot of empty space in there. I'd like to put in a shelf to store some less frequently used kitchen equipment. What would be the best method to build such a shelf? The cabinet walls seem to be 3/4" thick.
My first plan is this:
- Start with two pieces of plywood, a "left half" shelf and a "right half" shelf
- Cut a rectangular hole in each piece so that the exhaust duct can pass through the shelf
- Mount each half-shelf with right-angle brackets to the side wall of the cabinet
- Put a full-width edging strip of plywood at the front of the shelf, joining the two half-shelves
My woodworking tools and experience are limited – I'm at the cordless drill and hand saw level.
Is this a good plan? Are there other approaches I should consider? My main worry is whether I can anchor those wall brackets into 3/4" cabinet walls securely.

A 2 piece shelf is a good plan, but my scheme differs from yours from there. Yours would work, but mine's better (IMO). Instead of plywood, I would use MDF. It's dimensionally stable, easy to work, and paints up very nicely with a very smooth surface.
I would cut a circular hole to fit the duct closely so small things don't fall into the void below. Consider buying a small electric jig saw for sawing. It doesn't have to be very expensive, you will likely find other uses for it once you have one. And it'll save a ton of manual labor! Sell it on flea-bay when you're done if you really don't want it. This all can be done manually if you're a glutton for punishment.
You don't need angle brackets, though they could work. Gluing and screwing MDF cleats to the walls will be much stronger and probably more accurately assembled. You don't really need to attach to the cabinet sides at all. A cleat along the back wall and a front filler panel would be adequate support. If it's not too much trouble, the extra support would not hurt though. I would use construction adhesive for glue.
You will need to pre-drill all fastener holes in MDF. It's too dense to drive anything through it without doing so. You should not use glue to hold the actual shelves, screws alone will allow removal to access the range hood or retrieve items that fell through near the duct. You normally should never run fasteners into the edge of MDF, but in this case it's non-structural just to keep the shelves from moving. Be sure to pre-drill the full screw depth into the cleats because fasteners in the edge of MDF cause it to spall very easily if not pre-drilled.
