1) Do you know how heavy this mechanism is?
2) You have no information on the crusher or lifter
3) I doubt the lift and shake would work
4) I doubt it could shake out the electronics
5) How do you stop it shocking itself out?
6) On an unrelated note, Im getting quite fed up with all the informtion being put in the Notes area now. I think you should rename it Stats instead.
7) I understand you copied the idea from Martyn, and Ive noticed its the not the first design in progress you have cloned either...
Yes, I am back in rant mode!

Just my 2p...
