I'm with you 8Thumbs. I love my rotary vice (griffin oddessy) but use it most of the time in a stationary position. I do rotate for examining the fly, for tying on hard to get at stuff like rubber legs.

But, for spiral wrapping I'm more comfortable if I leave the vise stationary and use my fingers (I learned on and old Thompson model A) I don't like needing to half hitch the thread and find the bobbin cradle get's in my way.

Perhaps I am missing some rotary techniques, how do the rest of you manage the thread when using a rotary for spiral wrapping?
