Still looking for seed corn grader

A pic was shown of what the owner SAID was a seed corn grader. He didn't tell how it was operated, or whether it told what size corn it graded or sized. I have one exactly like it, but it dosent tell anywhere on it what size corn it grades IF INDEED it does grade corn.

I found on U Tubes one supposedly grading seed corn, but with an overseas E Mail. Tried to E Mail them, but it wouldn't go.
 
You could make a crude one with differing screen sizes set on a 'slope' with a vibrator of sort to help things to move along. Our local pinto bean elevators use a 'gravity table' to sort beans Works very well to separate rocks from beansIts a 'table of sorts set on an angle.It has some 'dividers' to help to direct the flow.The table vibrates.The heavy stuff seems to 'walk' up the grade,the lighter stuff drifts to the bottom.Sorry I have no pics.And I havent grown pinto beans for 25+ years,so I've not seen the outfit since.
 
That outfit in the picture he could not tell you that info because it is not a corn grader. It was used at the grain elevators when you delievered a load of grain, mostly soybeans as they usually had a lot of weeds that went to seed or the combine cutter bar hitting and picking up a lot of ground. When they would draw a sample to test for moisture and weight they tested for foren matter, the weed seed,you did not get paid for that weight. They would weigh out a sample as pulled from load in grams , not sure how many, they would hold that over a container and poor the grain sample in and shake it till there was no more dirt comming out. The grain that would not go thru it is what they weighed to get the test weight of the crop. The dirt that screened out with that was also weighed in grams. if you started out with say for ease of figuring 100 grans as pulled from load and after the sifting out of the dirt - weed seed, say you came up with 10 grams of dirt they figgured your load was 10% dirt so if the load was 1,000# they figured you had 100# of dirt or 900# of clean grain so you got paid for the 900# if the test weight was there, if not you got doct for a low test weight, after the moisture content was figured in. The holes were made just so the smallest beand would not fall thru but being long like they are if there was a half of a pod in the dirt it would work its way thru the slot to be counted as the dirt instead of as grain. If you had a lot of fine weed seed in a load of wheat they would have to use a different weed screen that the smaller size of the wheat would not fall thru but still the dirt would. Now if you had a lot of thisle pods in they would first use a screen that the wheat would fall thru with the small dirt and the larger dirt like the thisel pods would stay on top of the screen and they would be poored off to be combined with the dirt that would fall thru a screen the wheat would not and then both the small and large dirt would be subtracted in weight from the load and that is what you were paid for. In other words it is a dirt seperator.
 
If you have a fanning(clipper) type unit I would try it. Probably take a 2X2 top screen with a 3X3 middle screen and a 4X4 bottom screen to get some uniformity of size. I did that several years ago on O.P. indian corn that a guy wanted a certain size for feeding his racing pigeons. He wanted the real small stuff so I think I used a 3X3 top screen and my standard small grain bottom screen to get what he wanted. I get the screen material at the local older hardware store (the newer ones won't have the different odd sizes like 3X3).

I have a finger pickup type planter and simply shell ears, clean, and plant. Haven't had a problem yet with getting a decent, even stand.
 
How many bushels of seed are we talking here? Can you just make up some kind of manual shaker pan? Seams like Mother used to have one about twice the diameter of a pie pan. She used it for Lima beans or kidney beans or something. I think Pa made it out of some old perforated metal. Maybe an old fanning mill screen.
 
Im talking about around 4 to 5 bu. Im alone so I don't want to do it as was suggested. I don't see how one could look at corn 10 mins and be able to tell Med flats from Lg flats.

I have one of IHC earliest tractor planters, a 204
