Dodgers Shackles test 1

Ok iv bee looking at trying to cteate dodgers chains for his shackles so i have done some tests, iv used IK handles but they always seems to move only from one side and is not that useful for creating a chain that can move realisticly.
So i looked searched for tutorials for creating a chain in Maya, i came across this tutorial click to see tutorial. this tutorial was very simple and easy to follow so i produces this test. It uses riged body dynamics. By cleverly making the mock arms a parent of the nail constraints, i was able to animate these arms and the chain will follow, like so....



am now trying this on Dodger
