How does the true rotary function of a vise work in practice? Let's say I am going put some hackle on a fly. I tie it in, and now I decide to use the rotary function to wrap the hackle around the shank so the hackle doesn't twist (is it hard to keep it from twisting if you wrap it around the shank with hackle pliers?) I hang the bobbin on the bobbin hanger, and I start rotating the fly to feed the hackle onto it. What happens to the thread? Won't it twist around the fly too (or untwist)?
If you have a vise with a C-clamp isn't it a little awkward tying at the edge of a table with nothing underneath the vise? Is stability with a pedestal a big problem?
