Hi calum.
dont have any pictures of the crusher plate.
what I did to fix the bottom was drill and tap some 6mm holes at the bottom of the crusher plate.
I then used some 6mm bolts ( quite long) and put some heavy compression springs in between the plate and crusher box.adjusted lenght of spring to get correct angle on plate.
you will have to slot these holes through the box to allow a little up and down movement
job done.

cheers andy

Okay I think I understand what you mean, any idea what speed you will be running it at?

Hi calum.
un decided yet , have a 1200 rpm motor fitted but still waiting on belts for drive.
it appeared to work with battery drill on main fly wheel at around 400 rpm.

thats why I will power conveyors and crusher drive off power supply, so I can adjust on the fly to tune it with the material im running..

Cheers andy

Did you make yours like a cam? So it moves like this

Or did you just offset the bar so it pushes against the crusher plate and pivot it at the bottom?
