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.

Step 1: The Base

Step 2: Supports

Step 3: Exit

Step 4: The Arm

Step 5: More Supports

Step 6: Entrance

Step 7: Mill Supports

Step 8: Mills

Step 9: Motor and Gears

Step 10: Main Axle

Step 11: End!

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