I am finishing up my nine swarm traps from a large tube. They range from 24" to about 28" long, with an inside diameter of 10.5". The bottoms are nailed in, but the tops are removable. I made swarm lures with 1.5" pieces of drinking straws stuffed with cotton and soaked with LGO. Rather than messing around trying to attach pieces of comb vertically at the top, I just layed some down on the bottom (its primarily for the scent anyway). I know I will probably need to cut comb off the inside of the top and maybe the walls, but the tube was free (plywood is not)! I will post pics soon.
I look forward to seeing your pics. Free is always good.
Sounds like a good cheap trap.

Why not lay them horizontal and put a couple medium frames in them. Then you don't need to cut them out, which is a pain in the butt and sets the bees back as well.

I'm with Rob on this one.
That's a good idea! :)
Just came in from modifying some of the tubes so they can be horizontal. I put two deep frames in them; one with old drawn comb and the other with undrawn foundation, and held them in place with a drywall screw through the tube and into the top bar. Good thinking, Robo!
