I can pretty much guarantee that, unless you are handicapped somehow, if you were to spend 15 minutes with someone who knows how to use a bow drill to make fire and watched them do it, you would be able to reproduce successful results at will, depending on your availability of supplies.
Bowdrilling seems to be one of those things that is best mentored. You can develop the skill independently, but it takes a signifcantly greater time investment.
