I have finished the hive floor which deviates from the standard Warre floor design. I had little to go on other than a couple of sketchups and some pictures. Over the course of building the floor, I made some of my own modifications. The dimensions are:
Box: (2) 300mm x 110mm (2) 337mm x 110mm. I found these dimensions to work perfectly with 19mm thick lumber which is readily available in my neck of the woods
Floor: 337 x 337 mm recycled plywood
On the 300mm pieces, I cut 1/2 grooves about 25mm down along the entire length of the piece. I used these grooves as runners for the screened tray.
On the 337mm pieces, I ripped one piece at 25 mm which allows for a back bracket to be nailed in. The larger piece can then be removed to clean out the tray and floor. I used a thin piece of hardboard placed at the bottom to collect mites and debris.
I used a router on the other piece to cut a 120mm x 20mm entrance.
Instead of 100mm for the height, I chose 110mm which is a little higher, but it allowed me to cut a 120mm x 20mm entrance (front side) and still gave me space to place the tray while still allowing for some support on the back side.
The screen is #8 hardware cloth which prevents the bees from getting below the tray. I have posted pictures which can be seen here
