This is the inside of the sheller box, with the back of the angled slam board on the right side of the picture. The plenum top has been removed for the picture.

After the seeds hit the slam board and fracture along the seam, the meat falls to the bottom and most of the hulls blow out the open left side of the box.

In this picture, you can see some meats and a few unbroken seeds at the bottom of the box.

This is still a work in progress, and adjustments to slam speed and airflow through the box are on-going.

A genius at work. Great idea.

Wow! Did you study physics? This concept would never have occurred to me. How do you think building a shallow, rectangular box and a flat piece of wood with a couple of handles on the upper surface so that you could throw the SFSs into the box and hand-press them to remove/crack the hulls would work? I have no idea how you made a press for oil extraction. Thanks for posting!
