will this 4th axis work

[A_Camera]

Has anyone bought one of these harmonic drive index chuck thingies? Are they any good?

I am sure they are pretty good otherwise they would not be sellable.

Is the lack of a through shaft putting you off?

Yes. That and the fact that it is considerably more expensive.

Who will Magicniner contradict next?

I found his comments very informative and valuable. I don't know what you see was wrong with his comments or choice of words, but I did not find them contradicting, quite the opposite. I would actually be interested in hearing more about his experience and the modifications he did, as well as how he is using it.

So many questions, life is too short for all these questions.

...so why did you ask the last one then? It was pretty rude and unnecessary. His comments were pretty valuable, as opposed to your last question...
