Do as I say, not as I do........
We had given about half of our popcorn away, on the ear, to friends & family. We still had quite a bit left and the moisture level was getting to be just about right, that it needed shelled and sealed up for storage. Since the weekend was warm, I dug out an old hand crank sheller that we found in one of the buildings, when we were cleaning up this place.
There is one of these, where I grew up, mounted in the grainery. I was never a fan, they throw more corn around than you are able to catch. Looking at a lot of blistered thumbs, I decided to give it a try. I built a stand for it, so I could work outside, any kernels that got away would be picked up by the chickens, and I wouldn't have to clean up.
I rubber banded, safety pinned and tacked an old feed sack around the sheller to catch any stray kernels. I wasn't even sure this was going to work for popcorn, since the ears are so much smaller than regular field corn.
I got the sheller adjusted for the smaller ears and it worked great. We ended up with about 4 gallons of shelled corn, roughly 28 lbs.
12 ears yields about a quart, so I fugure we did about 200 ears in right around two hours. There was a fair amount of fooling around, every 2 or 3 qts we'd stop and pour the kernels back and forth between buckets, letting the corn fall a couple of feet, so the breeze would carry the chaff away.
If I was doing it by hand, I'd probably have a couple of dozen done by now.
I need to fabricate a better shroud, out of sheet metal, to contain the loose kernels, before next year. I probably lost about a quart of corn to the ground, it was an acceptable loss though, considering the speed we got done.
So I guess the new answer about how to shell popcorn is; if you have a half dozen ears, use your thumbs..... if you have a couple hundred, better locate something to give you an advantage.
