Rolling Arm Lift

finally here is the rolling arm lift. 
it is actually an combination between the rolling arm lift and the single mill lift. 
the last one can be replaced by another small lift, but here i show you this combination.
make sure you have enough motor power. i used an 12 volt motor, but it might be possible to drive it with two batterie motors.

now you have finished the rolling arm lift! 
i hope it was clear enough.
