Testing a swing animation in Stop motion

Yesterday I did a very rough test of a swing animation in stop motion. I used aluminium wire to make the chain and plasticine for the tire and attached the whole thing to a chair. It wasn't ideal but worked better than I thought it would. I think I might need to find a lighter material for the tire and make the chain a bit sturdier. The main challenge was getting the swing to stay in the right position as it tended to move down ever so slightly before I could grab a frame.

I also needed to figure out how the swing really moves. I made the mistake of just animating the entire construction at first but then I realized that there is actually a bit of secondary animation around the part of the chain which is directly attached to the tire. 
Nevertheless I am quite happy with this test.
