hi, i was wondering if anyone here has the Gonzalez Tortilla Machine. or if anyone has seen it while its working. I have a question about the way it works. How does the masa come through to the front of the machine? i guess what i want to know is how the masa is brought down, are both pillars spining or just one of them ? if any can help, it would be awesome. I saw a video of it working but i still dont know how it works, its for a school project that im working on.

Thanks
