Here is an excellent video series on Pancake armature truing and balancing. This video series is courtesy of Ron Schmidt. He posted this on Facebook. As we all know, finding posts on Facebook can be challenging, that said, I thought I would put the series here for future reference.

This is the best video series on this subject that I have seen. I would like to thank Ron Schmidt for taking the time to create these videos as well as his willingness to share his knowledge.!!! If you are interested in looking at this series then click the "read more" link.
