Of the two choices you mentioned, I would say the half inch hole. If you go that route, you will want to open the return door so cob pieces exit the machine. Actually, I don't think you need a special sieve for a super clean corn sample. If you set your cylinder_concave right - you can keep most cobs whole except for some small cob tips which you can close down the chaffer(top sieve) to eliminate them from the sample. Closing the chaffer will slow you down some in wetter cornIJ Start with 4 concaves bars in 1,2,3,5 positions, set cylinder at 3_4 inch, use the 13" pulley to drive the cylinder, run the cylinder at 600-800 rpms, close the chaffer down to only allow kernels, open the lower sieve all the way, open the air all the way, run a speed that gives you minimal returns. Make adjustments to the height of cylinder first, then try different cylinder speeds, or even adding no 4 concave for a total of 5. You should be able to get a very clean corn sample with these specs. It will crack some kernels, but you will burn them anywayIJ
