…“true rotary” vise??

simple terms please.

2

I would say a vice that allows the hook to rotate on its own axis, ie shank

3

A vice where the shank of the hook can be adjusted so that when rotated it rotates on the axis of the shank or center-line.

While “true rotary” function exists on many vices; I believe Renzetti coined the phrase and may have copyrighted it.

Even though you can do the rotary thing on a non-TRUE rotary vice; the wobbling of the hook shank is a pain in the butt.

4

Put a hook in the jaws with the shank in the horizontal plane. Rotate the vise head 180 degrees. If the hook shank is still horizontal it’s a “true rotary” vise. I like the term “inline rotary” better.

Here is a good video of true rotary in action: http://rotaryflytying.com/index.php?option=content&task=view&id=20

While, I don’t subscribe to the site, I did buy the DVD and found it very useful. Of the descriptions listed so far I have to agree with Jayatwork. A true rotary keeps the shank of the hook in one plane as it rotates so that you can tie while rotating. It is more than just the ability to rotate a fly so that you can see the bottom of the fly.

There you go. I’m gonna start using that phrase. I doubt I’ll ever have to explain it.

Now we just have to come up with a phrase to use for a vise that rotates along the jaw axis. I refuse to call it a non-true-rotary vise.
