Jaw Crusher Plans

Re homemade jaw crusher.I am very curious about whats its going to be.My ambition is however a 12x20 inch, to be driven by the pto of at least a 40hp tractor, so it can crush as fast as my 60hp tractor with loader can fill the feeder chute off course the vibratory grizzly feeder is the next stage, first get the crusher itself to run.
