I just thought I would post a couple of pics of my new sieve which I bought this October. If anyone hasn't seen one now you can see what its like. Sorry but my phone camera wouldn't get it all in. It seems a very well made piece of kit. Also there is a pic of my Hilco fan kit.
A friend on mine from Scotland says its the best machinery investment he has ever made, I will have to wait until July to try it!

Its a 1990 long shoe 1680. I have thought about the crossflow, but decided to modify the paddle fan due to cost for now. May change it in a year or two. I have the lower sieve set at 11/16 or 17mm as Marvin says, to get the air flow, that is why the conventional sieve is a problem isn't it. You shut the lower sieve to get a good sample then the air is cut to the top sieve. We have had too many returns in the past and hopefully this will solve it!

I'm sorry. Go with a 1'5/8 inch top seive & you have the same thing as you just bought. Had a customer had a air foil seive, I gave them a old top seive & they think it worked better then that old air foil seive did. Less adjustment more you can screw up. Just my thought's. Sorry MARVIN.

I got one year own marv's set up for the most part I am happy in sold stem wheat it sucks constanantly plugging up. Does give you exstreamly clean sample. I also had a couple of weed patches where this kept pretty much all the weeds out where on my other combine with a lowen air sieve it did not do near as good. anyway good luck

Marvin's "air-jet" is'nt even remotely close to the same setup as an "airfoil." In fact, one could allmost say it's opposite.

Greddy Guts what size screen did you get? Looks like it may be the .45 from the pictures, is that right? I have the .281, and the .250. I may purchase the .45s this year and see if it reduces the amount of straw that gets stuck in the screen.

I agree with ya, I think it is a well made unit. I like the stainless screens. It sure makes it easier to keep things shiny and polished over the winter. In small seeds like i run, the old galvanized stock chaffer would get all rough and where the galvy wore off, it would rust, making it difficult to set the machine for the first several acres.

Doorknob, You are right the holes are .45", Marvin said some in France like 9mm, but I stuck with what my Scottish friend had got as I am only 150 miles south of him and cut at similar conditions. Also .45 is better on barley. We also have a set of .25 inserts for Canola. My friend says it looks like its out of a cleaner apart from 1 piece of straw every few tonnes.
We have over 4t/acre wheat crops so there is alot of material for the sieve to sort out, that was the problem with the conventional set up, you overloaded the returns and then got higher losses.
I agree an airfoil is a different idea altogether.

Greedy Guts, ya ever see what this guy did? http://www.farmphoto.com/fpv2/message.aspx?mid=111064
Maybe not what you'd want to do, but looks like it solved his problems with overloading the tailings elevator.
