Just to let everyone know that the video on the split chain is now completed and uploaded onto YouTube. Here is the link http://www.youtube.com/watch?v=lPXkMb2BV2g and also there is a permanent link on the right side bar of my blog under Video Demonstrations.
I have also included in the video, a way of doing a split ring, using just one shuttle and the ball thread.
As YouTube only accept videos to a mazimum of 10 minutes I had to do a fair bit of editing. I hope this doesn't spoil your enjoyment of the film, but I have still managed to cover the necessities!
