This is a Cobblestone Factory that is in the tower style. There are some difference though. For 1 instead of just a lever shut of on the clock, a piston is set in place to turn off the clock. This gave me the ability to set up a control booth away from the clock. Also i put some furnaces above where the cobble stone pops up from the floor, so the stack of generated cobble does not get too high to mine. (in case you where wondering that last change does not effect the efficiency of the factory, because there is now way that one person could keep up with any way)

This factory does NOT destroy the cobblestone for you, when i test to see if pistons would crush them they just lagged and did nothing. So i'm sorry but you are going to have to get out the pick and mine it.

Additional Notes

If you need help using it, i am going to make a video soon.
