There's a section on planing method, also one on paper tuning. They adjust the arrows and adjust the bow. I'm fairly new to all this arrow stuff and only watched the DVD a couple days ago but it made sense and i think it's a great accompaniment to O.L.'s page. I'm now making some new arrows ready for tuning them and the bow and feel a lot more confident about the process after watching the DVD.
I also found both Barebow DVD's to be a great insight into the many different approaches to shooting trad bows, there's a lot of info in there.
