I'm looking forward to growing some buckwheat and some sunflower seeds and I've got a friend who lives in a populated area looking for a Kirby for me since I sold or gave away the one I had decades ago. Too bad the Kirby wouldn't work to shell this garbage bag full of black walnuts that is taking up space in my freezer. (or would it? hmm) Anyway, It'd be great if anyone who has a Kirby could experiment with seeds other than buckwheat and sunflower so a list could be compiled of what works with the Kirby method along with any slight modifications to the procedure such as optimal intake size. If some seeds don't work due to being too delicate then maybe an electrical engineer could design a speed control to lower the speed of the motor. I forget what type of motor is in the Kirby but I suspect it could not be slowed down by simply reducing the voltage but a variable frequency controller would probably work.
