I ‘had’ to try hanging something on the french cleat portion already up; so I picked my Stanley #6, 7, and 8 because they have stayed so buried I have not cleaned them up for use. I first picked out some likely lumber, a little eastern red cedar shorts from my mill, some left over 1/8” ply for a bottom, and an oak cleat from the left over pile.
I ripped the cedar down to 1-1/4” for the trays. There was so much tension in the wood it literally cracked apart as I cut it.
After some straightening, a trip through the TS with a dado blade, cutting the 45 miters, and cutting some ply for the bottoms; I had the tray sides and bottom.
Glued them up and cut the bracket pieces. A 3/8” piece of ERC, another piece of 1/8” ply to back it for strength, and the french cleat.
Glued and screwed that together, then glued and screwed it to the stray, and I have a plane holder for my french cleat storage system. It does not have finish on it yet. I am going to wait until the other 2 are done to finish them all together. I intentionally left the open knot hole in the front for character.
And this is why I am building all of this:
