I will say it is somewhere between 10 sec (wow!) and 1 hr 30 min (thanks for the vote of confidence!)

Like John said in the beginning, we went down about 6 rings and took all of that off the stave. So, while it was a fairly clean split, I didn't get to cheat on any portion of the back. The whole purpose of this demo was really to show that chasing a ring on Osage does not have to be tedious. What I did (and John recorded) was not amazing to people who work with Osage regularly. But I have heard people complain about how long that process can be, so I wanted to demonstrate the opposite is actually true.
The video that John will show is actually the second stave we worked. Our first attempt was unfortunately not recorded.

. So we picked another stick and did it a second time. I believe the first attempt was a bit faster, but not by much.
In any case, this was just me and John having fun, keep the guesses coming!
