Those are excellent nock & vane alignment tools. I've never seen the one from Archery Nock Tools before. That looks like a much better tool than the Apple tool that I have.

The tool that I am referring to straightens the nocks. Usually I can get to a 0.002 total runout. Most arrows start with about 0.012. Some better, some worse. Turning the nocks sometimes helps, but not always.

The nock straightening tool is not currently a part of Len's seminar. In fact when I described it to Len, he was a little dubious about it's effectiveness.

I'm just trying to drum up a little more interest in the seminar. Sorry if I have offended you.
