So, we went to the catalogs and internet. Kathy found a vintage, classic crank extractor on ebay for $75 starting price, with no bids. The photo and description indicated it has a few dings, has some definite rust spots but apparently the crank works ok. We looked at newer, smaller models at some of the beekeeping supply houses. Dadant has a metal, 2 frame job for about $150. We also could use the equipment at Indian Creek Nature Center in Cedar Rapids, where we are members and where we took the year-long course in beekeeping. We also looked at uncapping equipment and thought about ways of getting the bees off the frames. I found plans for a bee escape I can make called the vortex escape. Put that under the super, the bees think they are cut off from the rest of the hive and go through the escape but it is very difficult to get back. In several hours or a day, you can take the super off with few or no bees in it. Right now we prefer this method to using a chemical.
Later, I remembered that a former colleague of mine, Beth, and her husband, Jim, had kept bees years ago. I called them and Jim has given most of his equipment to his son, who is also in his first year of beekeeping. They would be happy to let us borrow their old extractor, though Jim gave the caveat "it's a lot of work!" I think we figured that would be the case having seen the extraction demonstrated at Indian Creek.
So, we're pretty excited with the idea that we indeed will have honey this season, maybe quite a lot actually. I'll take a better look at the frames next week and we may be doing some extraction in the next several weeks.
