To make a spare inside box for holding vaccuumed bees a shipping package for bees works wonderfully,
The package bees container is slightly larger but fits inside the vac cavity.
Place the container inside and mark the end where the bee vac hose inserts.
Drill a 1 and 1/2 hole.
Cut a 2 inch square piece of thin metal for the swiveling cover over the hose hole and bend like the original one.
Use the plywood cover that had previously covered the syrup can in original package to make a swiveling cover over the hole where can was.
Place a screw in metal swivel and a screw into a corner of plywood cover.
Tighten the screws so resistance holds the covers securely in place.
Works for me.
