This podcast has a review of my experience using Akerworks drop spindle tool called the Sprindle Crane.  They were a prize sponsor in the Tour de Fleece 2017 on Ravelry, and I had the very good fortune to win this prize!

Akerworks website for further information.

I promised a few links, here's the easiest to find on Youtube.

There is a difference between how the spinner in this video uses the spindle crane, and what I experienced.  I did not get the twist to go past the plastic threader when I worked with it.  I also used a hanging spindle instead of a supported spindle, although I do want to try the support spindle with it next.
