I got 2 5 gallon buckets. I perforated one bucket with 100+1/8 holes. I stack the perforated one inside the whole one and fill it with cappings. I put a lid on top and leave it in the bed of my truck for a few days during the summer. The honey heats up and dribbles out, the wax gets soft and compresses with a little elbow grease. After about a week, there's little left in the way of honey. I rinse out the remaining wax. I add some sugar back to the water I rinse the cappings with and feed it back to my nucs.
I'm certain the Capping's Spinner works well but with only 15 producing hives I can't justify the additional machinery yet.
I use a Dadant electric 20 frame extractor that I refurbished. I haven't seriously looked at the cappings bag as logically it would wobble like an unbalanced washing machine.
