Jack I weighed up the placement of the flow frames based on your observation and future build. I’m hope the colony will be strong enough to fill all of them. Otherwise I might be able to modify. Time will tell.
I’m going to cut down a metal queen excluder too. This one will slot in place next to the flow frames and not be moveable.
I’m hoping not to move it for a good while. If I need to in the future I’ll get some batons and tek screw or coach bolt them on.
