I found these guys in Holland making nutcrackers. The site is multi lingual and they ship all over the world.
I found a lot of nice and useful info on pressing oils and cracking nuts, especially time and yield info.
I haven't used one, so this is not a personal recommendation.
Only the native hazels are producing so far. Well, I'm going to get about ten Lake English Walnuts. I got only one the year before last. None last year. It's a young tree. It's amazing how much better they taste than the ones you buy in the store.
I have my own farm shop so I made one from scratch kind of based on a design that a guy has a YouTube video of where he's building one it looks like for English walnuts, mine is alot bigger and heavier duty . I bought a drill cracker a few years back it's a lot like the Davebilt cracker except you put a power drill hooked up to it for power and it works at First for the initial cracking but when you run it through a second time the nuts don't feed well. If you want to see my cracker go to YouTube and type in rays black walnut cracker. My dad came over and made a video of my set up. To me the other major factor is sorting nut meats so I built a separator table that my cracker dumps into. I still need a further sorting method so if anyone has some ideas I am all ears. Some guys I know are thinking of using carding cloth to pierce the meats for further separation.

I'll check out your video.
I saw a show about cashew production, it might have been Anthony Bourfain's. They were using a sharpened piece of wire to poke and lift the nut pieces. Might not work on walnuts, but it wouldn't be hard to try it out on the bigger pieces
No at that point it is pretty easy to hand sort as the separator table does over half the work already. A guy I know went Hammons for a tour and said at one stage they use a infrared eye that guides a air nozzle to blow pieces of shell out of the mix. I heard their cracking machine is hidden from public view but they do give tours. I'm sure Hammons spent lots of money on a team of engineers to design the system.
