I have screened.. Looking for slatted. Even though I could make them I would rather buy them. As the time I have is not all that much lately.

Skip the SBB and just tack screen on the bottoms of the slatted racks, that's what I'm doing this year. That way I have open bottoms, top entrances, and my hive stands are 4X4s stacked 3 high with a sheet of plywood on the bottom to keep weeds, or whatever, from growing into the hive. I also added a 1X2 just below the cross pieces so I can slip a piece of cardboard or veneer underneath to check for varrow. I made my first 2 hive stands today. I plan on making 8, I have 4 hives now, have ordered a package to teach my daughter how it's done, plan on making a duplex nuc for hold extra queens, and need a few just incase of swarm increase--mine or somebody else's. One less piece of equipment makes things simpler, and I like simple, being that way myself.
