I had been thinking of a good way to store those sink top inserts when parked. I was thinking of building one of those magazine rack style on the side of the cabinet.
But I noticed a blank spot above the drawer between the sink and oven. So I had to investigate. Which led me to removing the drawer and looking up in there with a flash light. Then just had to start unscrewing things.
So here is what I came up with.
Removed those two panels above drawer.
Ran top panel down table saw and reinstalled under counter.
Made a shelf out of some half inch ply. Cut some 3/4"x3/4" wood braces and secured with screws. I notched a hole in that ply panel holding up the drawer slides. Slid my shelf through the hole to wall. Cut a piece of solid 1/4" x4" oak and screwed it in for side panel to cover side of sink inside shelf area. Now just need to stain.
I store the stove tops in there and store the sink tops behind stove when parked. Always looking for extra space!
