I was looking at a metal lift catch dealie-o, but upon further mulling, realized I could thicken the lower chisel tray side pieces, place tenons onto their ends, and cut a hollow handhold on the side.
Here's an overview:
A closer look:
Now with the upper tray removed:
And here's a view of the lower tray sidepieces, with one wall removed so you can see the x-ray view of the inside of the handle/hollow:
I think this should work and it will be easy to make. It does add 4 more mortises and tenons mind you. It also means i can't fill up those side area of the tray as I need to leave enough room to get my hands in there. I figure a plane each side should be fine, and in the worse case scenario, i would have to remove a tool or two in order to get access to the handholds. Hopefully that won't, uh, be the case.
