In the video I put three used and recently repaired frames from one of our existing deep boxes and proceeded to shoot my video. Works as it says. To extract both sides of the frame in any centrifugal unit you will have to extract only one side of the frame at a time. The handle is removable from the top drive shaft. With a little MacGyvering one could instead possibly affix a wheel or gear and an electric belt driven motor and easily convert it but I’d use caution making it direct drive unless you include some sort of clutch engagement into the plan that also allows it to coast to a stop to save those softer metal gears in that drive box. All in all it’s fine for the money. There are more solid units out there. They are more than double and triple the price. Small and growing apiary’s will get some use out of this and if you grow your bee operation to a point, you won’t be using just a three frame extractor anymore anyway.
That’s the “buzz” as I see it on this one.
